Preface
> Structure of this Book
This book is divided into two parts. The first part (Chapter 1 & 2) covers basics of object-oriented programming & Java. This part is essentially written to give a kick start for Java novice and good refresher to brush off few core essentials of Java. It can be totally skipped by Java experts. The second part (Chapter 3 to Chapter 14) focuses on the actual certification examination.
Each part is further divided into chapters. Each chapter contains SCJP Objectives and the related concepts. This organization is intended to help you keep track of your SCJP preparation. This book is thus can be read from any chapter rather than like a novel to be read from cover to cover. Java concepts are discussed along with SCJP objectives. Hence you are likely to keep this book even after the SCJP certification, as it should serve as a good Java reference book.
You can read each chapter independently from the other chapters. Each chapter has an introduction that explains the general subject of the chapter, summarizes the SCJP objective learned in the chapter. It is followed by actual discussion of the related Java concepts. Each chapter has SCJP sample test at its end to help you assess your understanding immediately.
