From the Inside Flap This book is a collection of exams and detailed answer explanations. The questions, answers and explanations are designed to exercise, test, and expand your knowledge of the topics that are relevant to the Java programmer certification exam. This is not just another Java programmer certification study guide. Rather than present the fundamental concepts in the text of long, sleep-inducing chapters, the concepts are presented as explanations to specific mock exam questions. The reader is free to read only the explanations that are relevant to his/her specific needs. The chapter introductions are used only to list the concepts--not reteach them. You probably learned Java by reading one of many Java fundamentals text books, and you probably still have that book on your bookshelf. The book that you already have probably covers most if not all of the material necessary for the Java programmer certification exam. In fact, it probably covers far more material than the exam. This book will help you to quickly identify your strengths and weaknesses so that you can use your study time most effectively. This book is also for any university student who is studying Java programming. If you have started reading a Java fundamentals textbook, then you should be working through this book concurrently. This book will help you to master the important concepts that are relevant to the certification exam and most likely are relevant to your course exams. Did you learn Java on the job? If so, then you probably learned only what was necessary to complete the project at hand, and there are probably large gaps in your knowledge of Java fundamentals. This book will help you to identify the gaps in your knowledge so that you can improve your productivity and confidence in your abilities as a programmer. Are you getting ready for a job interview? This book will help you to prepare for the questions that might be asked during the interview. Don\'t be surprised if you fi
