This book is teeming with mistakes. Singleton implementations are broken(the current idiom for singleton is enum singleton, static class holder(described in this book) is an idiom for safe publication only, but it does not work for singleton because there can be several classloaders in JVM) - double checked locking in this book misses volatile keyword, which is crucial. Nevertheless, the book confirms that implementation does not work and says that "the problem was reportedly fixed in Java 5". Guys, I've bought this book for Java 7 certification, of course it should reflect changes made in Java 5.
The authors also do not distinguish the difference between widening of primitive types and upcasting of classes.
The sum() method on page 166 creates n Double object wrappers, instead of using primitive double variable etc. and so on.
This book also contains many groundless optimization tips, for example it states that final classes in Java are more efficient, because "the method calls are resolved in compiler time" . That is wrong for Hotspot JVM, because it's smart enough to apply analogous optimization looking whether the method is effectively overriden in subclass or not - it's done during the classloading and has nothing to do with final keyword.
You should not justify twisting your code only by a hypothesis that there may exist some JVM where some specific optimization *may* work.
P.S. sorry for my English I'm not a native speaker.

I was desperately looking for a book to prepare for OCPJP 7 exam and thanks to the authors/publisher for bringing this one. This is the first one and I think the only book available right now for OCPJP 7 aspirants like me. I started reading this book and surprised pleasantly by the contents. The FAQ chapter cleared all my doubts related to the exam. The quality of questions in pre-test (chapter 2) is decent. I then jumped to Generics chapter which is quite elaborated and adequately explained. The book contains two full size mock-tests that is the most desired thing. Although, a lot to be read to come to a conclusion, my initial experience is great. I am impressed.
