Java 2 Platform, Standard Edition 5.0, code- named "Tiger".

The Java platform has split into three branches (Standard, Enterprise, and Micro) and the JDK has been released to the open source community. The Java language has expanded to include annotations, generics, enumerations, advanced collections, and more. It has also begun to share its home, the JRE, with dynamic languages like Groovy, JRuby, and Rhino, to name a few. In fact, if you think about it, especially over the last few years, we've collectively watched as the moniker of Java has transformed from a language into a veritable platform.
