Review title: Excellent and Thorough
Product review: This book was extremely thorough in its preparation for the Certification Exam. I found it better on several topics (Threads, Collections) than several other books I read. The practice questions and sample exams were much more difficult (and therefore helpful) than others as well. Even now that I have become Certified, I keep this book around as a reference for some of the tricky language and API features. Definitely worth it, although I would supplement it with some of the good web sites and possible another book as well (I also read the Sybex one)
