Query: The fundamentals and Inner working of Java are explained

The fundamentals and Inner working of Java are explained very nicely. This book was the only book resource I used to study for the Exam. I passed the first time writing it.I studied approximately 2.5 weeks for the exam. The internet has good websites which helped alot by giving mock exams and tests (which are quite similar to the real exam).
