Java Programming?

Java is so vast, it's hard to claim one book. If you want to learn the ABCs of the language features: "Teach Yourself Java", Osborne publications by O'Neil. If you want to learn class structuring: "The Black Art of Java Game Programming" Wait Group, by Joel Fan (and others). The Sun on-line tutorials (downloadable) will lead you through the widgets of Java -- Swing.

Go to the public library, the coffeehouse bookstores and read a variety of books until you begin to see the similarities in all the tutorials.

I recommend a good IDE like NetBeans to take out some of the frustration of code completion.

And finally, implementation features of HOW to use the limitations of any computer language is to read other people's code.
