Query: Just what a beginner should have

I'm a beginner to the java environment, but not to the programming scene, and this book has been extremely helpful. You need to first realize though that this is a reference manual, not something that you can read from cover to cover and learn java in 21 days. It's a great source of information for the classes within java, and I'd highly recommend this to anyone who has C/C++ experience who wants to make that leap to java.
