Questions tagged [java-6]

Java SE version 6 was released in December 2006. Use this tag for questions specific to this version of Java.

Java SE 6 was an evolutionary change over the previous version. It did not include extensive language or JVM changes, however such changes were planned for Java SE 7 which was supposed to be released much sooner. (See here for what changed in Java 6).

As a stop-gap to the much delayed Java 7, Sun (since purchased by Oracle) introduced Java SE 6 Update 10, which despite its modest version numbering, represented extensive improvements to the GUI capabilities of Java in order to support JavaFX and Sun's renewed attempt to make Java successful in the GUI arena.

Internally, Java is numbered with a "1." before the number, so it will report itself as "1.6.0_" with an update number at the end. Starting with version 6, Sun dropped the ".0" from its marketed version number, so instead of 5.0 as previously done, it was Java 6.

Only use this tag if your question is specifically related to features of this version. Just because you are using this version, doesn't mean you need this tag. Use in addition to or instead of this tag.

See for more information.
