This book, however, really made my life easy. In the project I was working on, I knew pretty much
what I needed to do, and this book facilitated my understanding of Swing greatly. The text is filled
with examples and thoroughly documents each of the Swing components. I found it very helpful as a
supplement to the official Java documentation.

I hadn't read an O'Reilly book until this one and I have to say that I'm impressed. I'll be trying out some of their other books in the hopes that the quality carries over.
