I think you'd have a better chance of knowing (or finding out) what's on the AP exam than I would, since you're still in High School I take it. You can ask one of your teachers. I took the AP exam in HS and it was in Pascal. There was no sort of graphics programming. Everything was basics. I guess you can consider it "console programming." I believe C++ was the same way.
However, the Java Certification exam from Sun does cover the AWT. You have to know the basics of it, and that means how to initiate windows, colors, etc. (stuff you'd do for applets). I'm not sure if the AP would be the same way, but I figure I'd tell you.
If you want an online tutorial just do a search for "Java tutorial." (Duh

) The best book that I've come across with has been Beginning Java 2 SDK 1.4 Edition by Ivor Horton.

If you're going to buy a book, which I recommend, always look at reviews first before you buy. If you can't grasp concepts from a book, usually, it's not you. It's the author that can't explain.
