Java 1.4 vs. Java 5.0 in Industry

I am having some difficulty keeping both Java 1.4 and Java 5.0 in my head at the same time. There so many enhancements, rule relaxations, and new preferred approaches (e.g., generics) to Java issues that the danger of writing incorrect Java 1.4 code is significant for me. C and C++ do not present me with the same cognitive dissonance issues because they are really different from Java.

So I have to make a choice - which version to study in areas such as web programming, swing, collections, and j2ee. Has Java 5 made serious inroads into the working world or should the practical student stick to Java 1.4? How will this affect the interview process? What version of Java should be taught to students looking for a programming career in a year or two?

Thanks for your advice.

Stick with 1.4 for another two years. Get certified in 5.0 too.

For once I agree with Homer. People haven't made the leap to 1.5 for existing code bases yet. New projects are starting on it, though. In two years 1.5 will be the way to go.

Currently in my company we have already started classes in Java 1.5. We are currently standardized on eclipse and as soon as the 3.1 final comes out most if not all new projects will be done in 1.5.

Existing projects are planned to migrate to 1.5, but that is on a case by case basis.

I'm pulling on my collar like Rodney Dangerfield. I grew up in a tough, tough neighborhood.
I agree. Here's the link:
