Technical Review Superstars We don't know who burned the most midnight oil, but we can (and did) count everybody's edits-so in order of most edits made, we proudly present our Superstars. Our top honors go to Kristin Stromberg-every time you see a semicolon used correctly, tip your hat to Kristin. Next up is Burk Hufnagel who fixed more code than we care to admit. Bill Mietelski and Gian Franco Casula caught every kind of error we threw at them-awesome job, guys! Devender Thareja made sure we didn't use too much slang, and Mark Spritzler kept the humor coming. Mikalai Zaikin and Seema Manivannan made great catches every step of the way, and Marilyn de Queiroz and Valentin Crettaz both put in another stellar performance (saving our butts yet again). Marcelo Ortega, Jef Cumps (another veteran), Andrew Monkhouse, and Jeroen Sterken rounded out our crew of superstars-thanks to you all. Jim Yingst was a member of the Sun exam creation team, and he helped us write and review some of the twistier questions in the book (bwa-ha-ha-ha). As always, every time you read a clean page, thank our reviewers, and if you do catch an error, it's most certainly because your authors messed up. And oh, one last thanks to Johannes. You rule dude! Acknowledgements Kathy and Bert would like to thank the following people: All the incredibly hard-working folks at Osborne: Tim Green, Jim Kussow, Jody McKenzie, and Jennifer Housh for all their help, and for being so responsive and patient-well, okay, not all that patient-but so professional and the nicest group of people you could hope to work with. To our saviors Solveig Haugland and Midori Batten, for coming to our rescue when we were really in a bind! Some of the software professionals and friends who helped us in the early days: Tom Bender, Peter UNREGISTERED VERSION OF CHM TO PDF CONVERTER PRO BY THETA-SOFTWARE UNREGISTERED VERSION OF CHM TO PDF CONVERTER PRO BY THETA-SOFTWARE Loerincs, Craig Matthews, Dave Gustafson, Leonard Coyne, Morgan Porter, and Mike Kavenaugh.

Our great friends and gurus, Bryan Basham, Kathy Collina, and Simon Roberts. To Eden and Skyler, for being horrified that adults-out of school-would study this hard for an exam. To the Javaranch Trail Boss Paul Wheaton, for running the best Java community site on the Web.

Perface This book's primary objective is to help you prepare for and pass Sun Microsystem's SCJP certification for Java 5. The good news is that the exam does a good job of covering topics that most Java developers will encounter in their jobs. The challenging news is that the Java 5 exam is much broader in scope than its predecessor, the Java 1.4 exam. The new exam's objectives touch on many of the more commonly used of Java's APIs.The key word here is "touch." The exam's creators intended that passing the exam will demonstrate that the candidate understands the basics of APIs such as those for file I/O and regular expressions. This book follows closely both the breadth and the depth of the real exam. For instance, after reading this book, you probably won't emerge as a regex guru, but if you study the material, and do well on the self tests, you'll have a basic understanding of regex, and you'll do well on the exam. After completing this book, you should feel confident that you have thoroughly reviewed all of the objectives that Sun has established for the exam. In This Book This book is organized to optimize your learning of the topics covered by the SCJP Java 5 exam. Whenever possible, we've organized the chapters to parallel the Sun objectives, but sometimes we'll mix up objectives or partially repeat them in order to present topics in an order better suited to learning the material. In addition to fully covering the SCJP Java 5 exam, we have also included on the CD eight chapters that cover important aspects of Sun's SCJD exam. UNREGISTERED VERSION OF CHM TO PDF CONVERTER PRO BY THETA-SOFTWARE UNREGISTERED VERSION OF CHM TO PDF CONVERTER PRO BY THETA-SOFTWARE In Every Chapter We've created a set of chapter components that call your attention to important items, reinforce important points, and provide helpful exam-taking hints. Take a look at what you'll find in every chapter: Every chapter begins with the Certification Objectives-what you need to know in order to pass the section on the exam dealing with the chapter topic. The Certification Objective headings identify the objectives within the chapter, so you'll always know an objective when you see it! Exam Watch Exam Watch notes call attention to information about, and potential pitfalls in, the exam. Since we were on the team that created the exam, we know what you're about to go through! On the Job On the Job callouts discuss practical aspects of certification topics that might not occur on the exam, but that will be useful in the real world. Exercises are interspersed throughout the chapters. They help you master skills that are likely to be an area of focus on the exam. Don't just read through the exercises; they are hands-on practice that you should be comfortable completing. Learning by doing is an effective way to increase your competency with a product. From the Classroom sidebars describe the issues that come up most often in the training classroom setting. These sidebars give you a valuable perspective into certification-and product-related topics. They point out common mistakes and address questions that have arisen from classroom discussions. The Certification Summary is a succinct review of the chapter and a restatement of salient points regarding the exam. The Two-Minute Drill at the end of every chapter is a checklist of the main points of the chapter. It can be used for last-minute review. The Self Test offers questions similar to those found on the certification exam, including multiple choice, and pseudo drag-and-drop questions. The answers to these questions, as well as explanations of the answers, can be found at the end of every chapter. By taking the Self Test after completing each chapter, you'll reinforce what you've learned from that chapter, while becoming familiar with the structure of the exam questions. Introduction Organization This book is organized in such a way as to serve as an in-depth review for the Sun Certified Programmer for the Java 5 exam for both experienced Java professionals and those in the early stages of experience with Java technologies. Each chapter covers at least one major aspect of the exam, with an emphasis on the "why" as well as the "how to" of programming in the Java language. The CD included with the book also includes an in-depth review of the essential ingredients for a successful assessment of a project submitted for the Sun Certified Java Developer exam. UNREGISTERED VERSION OF CHM TO PDF CONVERTER PRO BY THETA-SOFTWARE UNREGISTERED VERSION OF CHM TO PDF CONVERTER PRO BY THETA-SOFTWARE What This Book Is Not You will not find a beginner's guide to learning Java in this book. All 800 pages of this book are dedicated solely to helping you pass the exams. If you are brand new to Java, we suggest you spend a little time learning the basics. You shouldn't start with this book until you know how to write, compile, and run simple Java programs. We do not, however, assume any level of prior knowledge of the individual topics covered. In other words, for any given topic (driven exclusively by the actual exam objectives), we start with the assumption that you are new to that topic. So we assume you're new to the individual topics, but we assume that you are not new to Java. We also do not pretend to be both preparing you for the exam and simultaneously making you a complete Java being. This is a certification exam study guide, and it's very clear about its mission. That's not to say that preparing for the exam won't help you become a better Java programmer! On the contrary, even the most experienced Java developers often claim that having to prepare for the certification exam made them far more knowledgeable and well-rounded programmer than they would have been without the exam- driven studying. .
