What is Java Programming?
Java is a high-level programing language and computing platform developed by Sun Microsystems. Since then, it has been considered as one of the most widely adopted programing languages. By having foundations in readability and simplicity, Java is the programming language of choice for creating long-term compatibility since it ensures older applications to continue working into the foreseeable future.
What is Java Programming Used for?
As the importance of web-based and mobile-based applications continually grows, Java is the foundation for most networked applications today and it is considered useful for scripting, web-based content, enterprise software, games, and mobile applications.
The versatility of Java is depicted in its wide use for developing different kinds of apps and systems, including:
Desktop GUI Applications
Java provides GUI development with the use of Abstract Windowing Toolkit (AWT), Swing and JavaFX. They provide number of pre-constructed components, a GUI widget toolkit, advanced components, a set of graphics and media packages, 3D graphic features, and self-contained deployment model which facilitates quick scripting of Java applets and applications.
Java Platform, Micro Edition (Java ME or J2ME) is a cross-platform framework for building applications that run across all Java-supported devices. Mobile apps for the Android operating system are written in Java, using the Android Software Development Kit (SDK) or other environments.
Embedded systems, such as SIM cards, utility meters and televisions, blue-ray disk players and more, all use embedded Java technologies.
The Java platform provides specialized support for web applications through Servlets, Struts or JSPs. Java enables easy programing and higher security which makes it excellent for development of government applications for health, social security, education, insurance, as well as ecommerce web apps.
Web Servers and Application Servers
The Java ecosystem enables development and support of web servers and java application servers. Server apps and servlets like Apache Tomcat, Simple, Jo!, Rimfaxe Web Server (RWS) and Project Jigsaw, and WebLogic, WebSphere, and Jboss EAP dominate the web and application server spaces respectively.
Enterprise Software Applications
Java has a separate Enterprise Edition (Java EE), which is a platform that provides API and runtime environment for scripting and running enterprise software. Among others, Java is used for development of financial and trading systems, and it is the backbone of a variety of banking applications.
Due to its versatility, Java is also able to run complex scientific calculations and mathematical operations. It is fast and secure and it has a high degree of portability and low maintenance, which makes it suitable for creating scientific software.
Advantages of Using Java Programming
Here are some of the advantages that Java offers:
High cross-platform functionality and portability
Java projects, programs and applications can be written in one platform, but can run across desktop, mobile devices, and embedded systems.
It is a free and simple object-oriented and distributed programming language which can perform several tasks at the same time, allowing java developers to write complex and interactive applications.
Java is a programing language which enables rapid development of scalable and complex applications. It can dynamically extend itself in order to expand functionalities and allow applications to extend and grow.
Java is supported with a well-designed intuitive set of APIs that allow programs to write codes faster and more efficiently, with fewer bugs. That enables a shorter time-to-market, thus lowering development costs.
