Excellent tutorials! Thanks so much for your great work!
Four  ideas/suggestions
1) JRuby: Up and coming.  Recent buzz.
2) UML: Using UML type stuff on eclipse
for myself:
3) Inner Classes: little hazy on inner classes (not sure why use a class instead of the class's object inside a class). Would be nice if you covered it in one of your lessons.
3) Nonlinear program flow: (short) tutorials on how to avoid the common pitfalls of event driven program flow and asynchrous GUI calls for those of us used to linear program flow.

Once again thanks. Keep up the good work.
