Using Java 5 Features in Older JDKs

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."

Fun but not massively practical

I've worked in a an environment where 1.4 and lower is mandatory. This was down to management believing that 1.5 was too new and 'untested' even though Sun obviously thought it production worthy.

These kind of people would be very scared if you tried to write code using 1.5, recompile the byte code using some new-ish open source toolkits and then putting it in to production. Then again, you could do it without telling anyone. :)

the bleeding obvious... pointed out...

Java 1.6 is out now. 1.5 is so, like, last year.
