Query: This book is all you need to pass the Java exam

I passed the exam with 88% thanks to this book. It covers everything you need to know, and even though it is very detailed it is extremely readable. The author gets right to the important information without wasting pages on the "filler" material that is in so many programming books. The only weak points of the book, in my opinion, are the chapters on Event Handling and File I/O which seem rushed and not as informative as the other chapters. However, there is still enough information to pass the exam with no problem if you carefully study this book and its sample questions.
