Using Java 5 Features in Older JDKs

Posted by Hemos on from the if-you-had-to-of-course dept.

BlueVoodoo writes "Java 5 added a number of powerful language features: generics, enumerations, annotations, autoboxing, and the enhanced for loop. Even if you're stuck on JDK 1.4, you can still use generics. Use Java and theory to learn how."

  1. These have been around for years by ghoti · · Score: 4, Informative

    It's great that IBM is writing this, but these tools have been around for years. They basically came out the same time as the final release of Java 1.5 (or "5.0"), when many people realized that it would be tricky to deploy programs that were using the new features. By now, everybody should have updated to 1.5 anyway.

    Java 1.5 was released 09/29/2004, so it's over two years old. 1.6 was release 12/12/2006.

  3. Retroweaver has more features than reported by xlv · · Score: 5, Informative

    I'm the current maintainer for Retroweaver and the article does not mention all the Retroweaver features:

    Annotations are supported, the concurrent backport is used for the concurrent packages, runtime classes can provide support for new features or replace classes entirely, ...

    I suppose the article is based on the 1.2.5 version and not the beta version(s). I guess I followed the Google model of having a really long beta cycle with a stable product...

    Seeing the possible confusion with the Beta tag, I just decided to release the official 2.0 version earlier today.
