help learning java

I want to take a Java class, but I'm having trouble finding one that is both short enough and cheap enough to suit my needs. I've got a programming background, already know object orientated programming (C++), and already have rudimentary java skills. I need a class that will teach me things like how to make buttons properly interact with command line output, etc. I'd like a class of 2-3 days, or something in the evenings. I think I can get work to pay for it, but it should still be less than 1K.

Any thoughts?
