I have been converting a lot of code to the new JDK 1.5 constructs recently and I decided it was too tedious, so I wrote a quick Eclipse plug-in to assist me.  It’s called J15 (“J One Five”) and I am happy to announce its first release.

Right now, J15 can convert for loops on arrays and collections but I have quite a few other enhancements in mind which I will disclose as I implement them.

In the meantime, please test it and let me know how it works for you, as I am confident there are quite a few cases that I haven’t covered (manipulating a Java Abstract Syntax Tree is fun but it produces very ugly code…).

By the way, you will need a recent Eclipse build to run it (since it needs to support these new constructs).  I am currently running N20040806 which passed all the Windows tests.
