However, loading preferences depends on the Search Engine manager, because the default search engine preference uses the search engine manager; we therefore need to ensure that preferences aren't loaded until search engines are loaded, to avoid potential hangup of the application for a fresh install. The following optimized code first initializes the search engine manager and then loads preferences.\n\n### Response:\n ```java\n \/* -*- Mode: Java; c-basic-offset: 4; tab-width: 20; indent-tabs-mode: nil; -*-\n * This Source Code Form is subject to the terms of the Mozilla Public\n * License, v. 2.0.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given kotlin program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

However, loading preferences depends on the Search Engine manager, because the default search engine preference uses the search engine manager; we therefore need to ensure that preferences aren't loaded until search engines are loaded, to avoid potential hangup of the application for a fresh install.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given kotlin program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given javascript xml program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given javascript xml program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given kotlin program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

If the ports are free, then the scanning will quickly finish. There could be some bottleneck ports that are busy causing the code to stall, as the timeout is set to 4 seconds (4000 milliseconds). One way to improve the execution time is to decrease this timeout value by a small amount. Note that we still need some non-zero timeout value to avoid raising and handling exceptions unnecessarily. The following optimized code sets the socket timeout value appropriately.\n\n\n### Response: \n```java\n package com.aaronjwood.portauthority.runnable;\n\nimport android.util.Log;\n\nimport com.aaronjwood.portauthority.response.HostAsyncResponse;\n\nimport java.io.IOException;\nimport java.net.InetSocketAddress;\nimport java.net.Socket;\nimport java.net.SocketException;\n\npublic class ScanPortsRunnable implements Runnable {\n\n    private static final String TAG = \"ScanPortsRunnable\";\n\n    private String ip;\n    private int startPort;\n    private int stopPort;\n    private HostAsyncResponse delegate;\n\n    public ScanPortsRunnable(String ip, int startPort, int stopPort, HostAsyncResponse delegate) {\n        this.ip = ip;\n        this.startPort = startPort;\n        this.stopPort = stopPort;\n        this.delegate = delegate;\n    }\n\n    @Override\n    public void run() {\n        for(int i = this.startPort; i <= this.stopPort; i++) {\n            try {\n                this.delegate.processFinish(0);\n                Socket socket = new Socket();\n                socket.setReuseAddress(true);\n                socket.connect(new InetSocketAddress(this.ip, i), 3500);\n                socket.close();\n                this.delegate.processFinish(i);\n            }\n            catch(SocketException e) {\n                Log.e(TAG, e.getMessage());\n            }\n            catch(IOException e) {\n                Log.e(TAG, e.getMessage());\n            }\n        }\n    }\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the execution time.

However, loading preferences depends on the Search Engine manager, because the default search engine preference uses the search engine manager; we therefore need to ensure that preferences aren't loaded until search engines are loaded, to avoid potential hangup of the application for a fresh install. The following optimized code first initializes the search engine manager and then loads preferences.\n\n### Response:\n ```java\n \/* -*- Mode: Java; c-basic-offset: 4; tab-width: 20; indent-tabs-mode: nil; -*-\n * This Source Code Form is subject to the terms of the Mozilla Public\n * License, v. 2.0.

However, loading preferences depends on the Search Engine manager, because the default search engine preference uses the search engine manager; we therefore need to ensure that preferences aren't loaded until search engines are loaded, to avoid potential hangup of the application for a fresh install. The following optimized code first initializes the search engine manager and then loads preferences.\n\n### Response:\n ```java\n \/* -*- Mode: Java; c-basic-offset: 4; tab-width: 20; indent-tabs-mode: nil; -*-\n * This Source Code Form is subject to the terms of the Mozilla Public\n * License, v. 2.0.

This client provides access to those\n    primitive types in a generic way.

The global statement is used to specify that assignments to that name are assignments to the variable in the global (module) scope, rather than in the local scope.

If the constant behavior is indeed required, use the Boolean literals True or False, rather than encoding them obscurely as 1 == 1 or similar.

Other commands in the function then append values to the list. The next time the function is called, the list will contain values, which may not have been intended. The recommended workaround is use a placeholder value. That is, define the function with a default of default=None, check if the parameter is None and then set the parameter to a list. The fixed code is: \n\n\n### Response:\n```python\n  def __init__(self, name, choices=[], default=None, shortDesc=None, longDesc=None, hints=None, allowNone=1):  \n       self.choices = choices\n      if default:\n           default=[]\n       if choices and not default:\n           default.append(choices[0][1])                   # value of 'default' parameter modified\n       Argument.__init__(self, name, default, shortDesc, longDesc, hints, allowNone=allowNone)\n```\n\n### Instruction:\nRewrite the given Python program to avoid the Modification of parameter with default CodeQL warning.

The global statement is used to specify that assignments to that name are assignments to the variable in the global (module) scope, rather than in the local scope. At the module level, this statement is redundant because the local scope and global scope are the same. Hence, we can remove the global statement.

In the part of the code, it does the actual download of a given block, by processing the block in chunks of size DownloadMission.BUFFER_SIZE. To check if the download is not yet complete it employs the check 'start < end && mMission.running && (len = is.read(buf, 0, buf.length)) != -1'.

The entire index is only on about 5 lines, thus the 5th line is about 2mb. The solution here is to switch to reading a fixed length of 4096 characters at a time rather than entire lines. Use a custom tokenizer rather than Java String methods such as indexOf.

In the part of the code, it does the actual download of a given block, by processing the block in chunks of size DownloadMission.BUFFER_SIZE. To check if the download is not yet complete it employs the check 'start < end && mMission.running && (len = is.read(buf, 0, buf.length)) != -1'.

Write the entire code and no other text in the response.\n\n### Concepts:\n[+] item.state\n[hint] We need to delete the download destination first, otherwise Android appends -1, -2, etc. to the destination instead of overriding the file as intended.\n\n### Given program:\n```java\n\/* Copyright (C) 2016 Julian Andres Klode <jak@jak-linux.org>\n *\n * This program is free software: you can redistribute it and\/or modify\n * it under the terms of the GNU General Public License as published by\n * the Free Software Foundation, either version 3 of the License, or\n * (at your option) any later version.\n *\/\npackage org.jak_linux.dns66;\n\nimport android.app.DownloadManager;\nimport android.content.Intent;\nimport android.net.Uri;\nimport android.os.Bundle;\nimport android.support.v4.app.Fragment;\nimport android.support.v4.view.ViewPager;\nimport android.support.v7.app.AppCompatActivity;\nimport android.support.v7.widget.Toolbar;\nimport android.util.JsonReader;\nimport android.util.JsonWriter;\nimport android.util.Log;\nimport android.view.Menu;\nimport android.view.MenuItem;\nimport android.widget.Toast;\n\nimport com.aurelhubert.ahbottomnavigation.AHBottomNavigation;\nimport com.aurelhubert.ahbottomnavigation.AHBottomNavigationAdapter;\n\nimport org.jak_linux.dns66.main.MainFragmentPagerAdapter;\n\nimport java.io.File;\nimport java.io.InputStreamReader;\nimport java.io.OutputStreamWriter;\n\npublic class MainActivity extends AppCompatActivity {\n    private static final int REQUEST_FILE_OPEN = 1;\n    private static final int REQUEST_FILE_STORE = 2;\n    private static final int REQUEST_ITEM_EDIT = 3;\n\n    public static Configuration config;\n    private ViewPager viewPager;\n    private AHBottomNavigation bottomNavigation;\n    private ItemChangedListener itemChangedListener = null;\n\n    @Override\n    protected void onCreate(Bundle savedInstanceState) {\n        super.onCreate(savedInstanceState);\n\n        if (savedInstanceState == null) {\n            config = FileHelper.loadCurrentSettings(this);\n        }\n        setContentView(R.layout.activity_main);\n\n        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);\n        setSupportActionBar(toolbar);\n\n        viewPager = (ViewPager) findViewById(R.id.view_pager);\n\n\n        int[] tabColors = {R.color.colorBottomNavigationPrimary, R.color.colorBottomNavigationPrimary, R.color.colorBottomNavigationPrimary, R.color.colorBottomNavigationPrimary, R.color.colorBottomNavigationPrimary,};\n        bottomNavigation = (AHBottomNavigation) findViewById(R.id.bottom_navigation);\n        AHBottomNavigationAdapter navigationAdapter = new AHBottomNavigationAdapter(this, R.menu.bottom_navigation);\n\n        bottomNavigation.setForceTitlesDisplay(true);\n        navigationAdapter.setupWithBottomNavigation(bottomNavigation, tabColors);\n\n        reload();\n\n        bottomNavigation.setOnTabSelectedListener(new AHBottomNavigation.OnTabSelectedListener() {\n            @Override\n            public boolean onTabSelected(int position, boolean wasSelected) {\n                Fragment currentFragment = null;\n                if (wasSelected) {\n                    return true;\n                }\n\n                viewPager.setCurrentItem(position, false);\n                return true;\n            }\n        });\n    }\n\n    @Override\n    public boolean onCreateOptionsMenu(Menu menu) {\n        \/\/ Inflate the menu; this adds items to the action bar if it is present.\n        getMenuInflater().inflate(R.menu.main, menu);\n        return true;\n    }\n\n    @Override\n    public boolean onOptionsItemSelected(MenuItem item) {\n        \/\/ Handle action bar item clicks here.

SmoothListFragment extends ListFragment, so we should do this unregistration by overriding the onDestroyView method. To ensure the unregistration is properly done, we have to invoke the corresponding parent class's method before exiting. The resulting code with proper memory handling is as follows.\n\n\n### Response: \n```java \npackage be.digitalia.fosdem.fragments;\n\nimport android.os.Build;\nimport android.support.v4.app.ListFragment;\n\n\/**\n * ListFragment which disables the fade animation under certain conditions for more smoothness.\n *\/\npublic class SmoothListFragment extends ListFragment {\n\n\t@Override\n\tpublic void setListShown(boolean shown) {\n\t\tif ((Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) && isResumed()) {\n\t\t\tsuper.setListShown(shown);\n\t\t} else {\n\t\t\tsetListShownNoAnimation(shown);\n\t\t}\n\t}\n\n\t@Override\n\tpublic void onDestroyView() {\n\t\t\/\/ Ensure the ListView is properly unregistered as an observer of the adapter\n\t\tgetListView().setAdapter(null);\n\t\tsuper.onDestroyView();\n\t}\n}\n```\n\n### Instruction:\nRewrite the given java program to optimize and improve the memory usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given c program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given c program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given assembly program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given c program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given scala program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given scala program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given python program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given objectivec program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given c program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given ino program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given ino program to optimize and improve the energy usage.

This is potentially inefficient in terms of power usage. One way of optimizing the code is to check and notify the sensor readings at certain intervals, and disable the sensors at other times. To do this, we should first determine the measurement intervals, declare it is a variable that can be tweaked later if needed. We can use the 'setInterval' function to enable the sensor at determined frequency. In the main code (discover method call), we first check and log the sensor values on the 'humidityChange' event, send the values using the defined 'send_to_keenio' function, and disable the sensors at the end of the event. The resulting code optimized for power savings is as follows.\n\n\n### Response:\n```javascript\n \n\/\/ 20 seconds in milliseconds\nvar measurementIntervalMs = 20000;\n\nvar keen = require('keen.io');\nvar SensorTag = require('sensortag');\n\nvar keen = keen.configure({\n \u00a0 \u00a0projectId: process.env.keen_io_projectId,\n \u00a0 \u00a0writeKey: process.env.keen_io_writeKey\n});\n\nvar uuid = process.env.sensortag_uuid;\n\nfunction send_to_keenio(temperature,humidity,uuid) {\n \u00a0 \u00a0console.log(uuid + ' \\ttemperature = %d \u00b0C', temperature);\n \u00a0 \u00a0console.log(uuid + ' \\thumidity = %d %', humidity);\n\n \u00a0 \u00a0var eventdata = {};\n \u00a0 \u00a0eventdata[\"SensorTag \" + uuid] = [\n\t{\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"temperature\": temperature,\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\"humidity\": humidity\n \u00a0 \u00a0 \u00a0 \u00a0}\n \u00a0 \u00a0];\n \u00a0 \u00a0keen.addEvents(eventdata, function(err, res) {\n\tif (err) {\n\t \u00a0 \u00a0console.log(\"Error sending to keen \" + err + res);\n\t}\n \u00a0 \u00a0});\n};\n\nconsole.log('Init, discover uuids ' + uuid);\nSensorTag.discover(function(sensorTag) {\n \u00a0 \u00a0var uuid = sensorTag.uuid;\n \u00a0 \u00a0console.log(uuid + ' Discovered');\n \u00a0 \u00a0sensorTag.connect(function() {\n\tconsole.log(uuid + ' Connected');\n\tsensorTag.discoverServicesAndCharacteristics(function() {\n\t \u00a0 \u00a0console.log(uuid + ' DiscoverServicesAndCharacteristics');\n\t \u00a0 \u00a0sensorTag.on('humidityChange', function(temperature, humidity) {\n\t\t\/\/ Ignore readings of a disabled sensor\n\t\tif (temperature == -46.85 && humidity == -6) {\n\t\t \u00a0 \u00a0return;\n\t\t}\n\t\tvar temp = temperature.toFixed(2);\n\t\tvar hum = humidity.toFixed(2);\n\t\tsensorTag.disableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Got reading, humidity sensor disabled for ' + measurementIntervalMs + ' ms');\n\t\t});\n\t\tsend_to_keenio(temp,hum,uuid);\n\t \u00a0 \u00a0});\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0setInterval(function() {\n\t\tsensorTag.enableHumidity(function() {\n\t\t \u00a0 \u00a0console.log(uuid + ' Humidity sensor enabled to get the next reading');\n\t\t});\n\t \u00a0 \u00a0}, measurementIntervalMs);\n\t \u00a0 \u00a0\n\t \u00a0 \u00a0sensorTag.notifyHumidity(function() {\n\t\tconsole.log(uuid + ' Humidity notifications enabled');\n\t \u00a0 \u00a0});\n\t});\n \u00a0 \u00a0});\n}, uuid);\n\n\n```\n\n### Instruction:\nRewrite the given ino program to optimize and improve the energy usage.
