A good, comforting religioius text would also help...
I have a copy of the Java Black Book by Steven Holzner (Coiolis). It is based on JDK 1.2, but, as a reference (especially for those of us who aren't object oriented yet) it is real good in that there is a little fluff and lots of examples and breakdowns of how to use the classes and what the (basic) methods do and such. (I'm an old tech geek in a new world, so I need it as simple as possible.)
