Title: Necessary but annoying sometimes
Review: Like the other reviewers, I agree you need this for the most efficient path toward passing the exam. BUT it has several ( 3 so far in 1st half of book) imprecise explanations which can lead to incorrect answers on the exam.I was not so critical until I received a rather terse reply from the author. He wrote "you know what I mean".I suggest if that is what the author truly feels and he wasn't just having a bad day, then you should not rely on this as your only guide. Get something that is more definitive ( e.g. Java 2 certification study guide )to double check the definitions and explanations in this book.
