博客介绍了J2SE 1.5语言特性的早期访问原型实现，该版本支持JSR014、JSR 65和JSR 201等相关特性，引入了泛型和数组类型的方差概念。可从指定链接下载，需J2SE 1.4.1及以上版本，还提供使用示例，对期待Tiger beta版的人是福音。

An early access prototype implementation of new J2SE 1.5 language features is available. In this version of prototype for JSR014, JSR 65 Concise Object-Array Literals (usually referred to varargs) and JSR 201 Extending the Java Programming Language with Enumerations, Autoboxing, Enhanced for loops and Static Import are also supported. In addition, Variance concept for generic types and array types are introduced so that you may program Java codes in a more abstract and integral fashion.

You can download this exciting implementation from http://developer.java.sun.com/developer/earlyAccess/adding_generics/index.html

It requires J2SE 1.4.1 or later and provides some examples on how to actually use enum, varargs, foreach style loop, boxing-unboxing, static import, and so on.

This early access must be bliss for those who can’t wait for Tiger beta which is going to appear in 2003 4th quarter.
