A Programmer's Guide to Java Certification

It is the best book I have ever read on core java!...If you are looking to understand the language thoroughly, to the perfection, then this is THE book for you!!

Khalid Mughal,Rolf Rasmussen, A Programmer's Guide to Java Certification: A Comprehensive Primer is a great certification book. It contains challenging mock exam questions, which were slightly tougher that I had expected and hints on how to get the best results. I found these especially useful in consolidating my knowledge of the subject. A comprehensive guide covering all important topics for Java Programmers means that this book is not only for first time Java users. If you want to master the Java programming language then this is definitely the book for you. This well organised book is structured into chapters, each covering an exam objective. However if you only need a minimal understanding of Java then you may find this book too much. The included CD simulates exam conditions giving you a real feel for what the exam will be like. All in all a great teacher and highly recommended.
