Although somewhat outdated this was a good tutorial book for Java 8. This book is not for an absolute beginner. I think some knowledge of programming is needed. I really appreciated how Cadenhead reminded what steps to use even with the IDE. I tried using a different book to get information about Swing and it didn't work at all. The code in this book worked, mostly. The code that did not work depended on online resources that have changed since the book came out. Although I was excited about the Android tutorial. It did not work as well. I think again because the codebase and the program changed.

Overall I found this book to be helpful, informative, and a good support to my efforts to learn java. Although I already knew Java, Cadenhead introduced many new areas. Overall I find this book to be worth the effort.

Will not help you pass a Java computer science class. It's mostly theory and not practical.
