Query: Good book gets you up to speed fast

If you are looking for a book that gets you up and running with Java really fast, this is it. While the book could be tighter in many places, remember that publishing for a fast moving technology is a tradeoff. You either come up with a very good book that is awfully late or a mediocre book that is a rush job. I would give the authors 75 points out of a possible 100.I like the book because it teaches through examples. Most of the book is filled with examples and their annotations. In some ways this bottom-up approach is more preferable to initial learning than the top-down approach of theory first and then examples.This is a good book for beginners and intermediate level programmers. I do hope that the book was less expensive.
