Query: Java precisely... and efficiently

This book reveals the true meaning its title "Java precisely". I wish all authors could learn from the beauty and teaching methodology of this book. Everything is explained with sheer simplicity, without making matters more complicated than they should be. It is very concise and to the point, without any unnecessary waste of paper. So many computer books are becoming bloated and heavy without offering any substance. As one of the other reviewers mentioned, this book reminded me of the K&R book of C. I can't wait to see more "Precisely" titles.
