Be careful. The HF S&J book is FULL of errors. Look at the errata for it on Oreilly.com. Questions cover information not in the book, numerous solutions are wrong, etc. It reads like a rough draft that wasn't ready to print, but was rushed through to meet a deadline.
I don't think K&B actually wrote any of this book. I'm pretty sure Bryan Basham wrote it and got K&B to sign onto it. It is not nearly as good as HF Java, HF OOA&D or HF Design Patterns.
You can also read the reviews on Amazon. Unfortunately, there aren't any other real options for SCWCD, but just don't expect a book nearly as good as the SCJP book which I loved.
I'm not a book basher, but this one needs help.
