This book is about learning the core concepts and key areas of Java/JEE development through questions and answers approach. This book will be a very valuable companion for all Java/J2EE practitioners and it is evident from the following:

"I have read several technical books over the last few years, but this one was entirely different. The questions and answers format was something which I had not seen in any other book and wasn't sure if would help either. But I was wrong. The objective of the authors is great, to help Job seekers as well as interviewers; and I think they have succeeded in doing so. They have compiled several questions and answers, and also have very good tips on how to face an interview." - By Meera Subbarao at IT Book Zone Team Leader
