A: Yes. There are a lot of good Java books on the market. You don't need have many Java books. The following is my recommendation:

1) Thinking in Java

Bruce Eckel / Prentice Hall / 2000 / 0130273635 / 2nd Bk&cdr

This book contains in-depth thinking about Java languages.

If you want to save money, you may download an electronic copy from www.mindview.com.

2) Core Java 2, Volume 1, Fundamentals;
Core Java 2, Volume 2, Advanced Features

Cay Horstmann, et al / Prentice Hall / 1999 / 0130819336 / Bk&Cd Rom

These two books contain comprehensive coverage of Java language and many of their examples are valuable.
