A Generic Java Language ExtensionCurrent compiler version: 0.6mGJ is an extension of the Java programming language that supports generic types.
GJ was designed by Gilad Bracha of JavaSoft, Martin Odersky of the University of South Australia, David Stoutamire of JavaSoft, and Philip Wadler of Bell Labs, Lucent Technologies. Although JavaSoft employees contributed to its design, GJ is not a product of JavaSoft or Sun Microsystems and neither JavaSoft nor Sun Microsystems makes any claims regarding it. Sun proposes to add generic types to JavaSun has put forward a proposal to Add Generic Types To The Java Programming Language as part of the Java Community Process. GJ is one of the leading proposals being considered. The process is spearheaded by Gilad Bracha, one of the GJ designers. Sun maintains a Bug Parade where users can vote to give feedback on which shortcomings in Java they would like to see fixed. A request to add generics to Java is bug number 4064105, and is in The Top Twenty-five Requests for Enhancements.

GJ is an excellent design and implementation for adding generic types to the Java programming language. It provides a workable and practical facility for the immediate future that can solve many of today's problems in programming and debugging. In the long term, I would hope to see it compatibly extended to carry run-time type parameter information in the manner that Robert Cartwright and I have proposed; but even if that does not occur, GJ as it is currently designed is a useful and workable tool that deserves widespread study and use. -- Guy Steele (quoted from e-mail, with permision) Also: Guy Steele's delightful keynote address at OOPSLA 98, Growing a Language, argues that Java will age better if it is extended to include operator overloading and generic types.
