For the past 20 years I&amp;#x27;ve had a career built on a solid API that doesn&amp;#x27;t change every 2 years like some flavour-of-the-month Javascript framework.&lt;p&gt;Even on the client where Java has lost to Javascript, I&amp;#x27;m finding it more enjoyable to add features to my 15-year-old SWT app [0] rather than dealing with the multiple layers of abstractions that is  Javascript+CSS+DOM (+ maybe Electron).  
Personally I think it&amp;#x27;s a shame Sun dropped the ball with client Java - if they had chosen SWT over Swing and provided a minimal JVM then maybe Java Web Start would have beaten Javascript web apps. It&amp;#x27;s also a shame Sun sold Java to Oracle - Google would have been a better steward, and probably would have been willing to pay more for the Java parts of Sun.&lt;p&gt;I&amp;#x27;m now trying Dart to develop a few Flutter apps.  It&amp;#x27;s no doubt a better language, but not &lt;i&gt;that much&lt;/i&gt; better - I think Flutter would have been more successful if it was built on Java.&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.solaraccounts.co.uk&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.solaraccounts.co.uk&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Java 12</title><url>https://jdk.java.net/12/</url></story>
