Based on the online version that has become one of the world's most visited programmer documentation sites, this is a remarkably clear, practical, hands-on introduction to the Java 2 Platform. The bonus CD-ROM contains all major versions of the Java Platform.

Mary Campione was formerly a senior technical writer at Sun Microsystems, where she started writing about the Java platform in 1995. Mary graduated from California Polytechnic, San Luis Obispo, with a B.S. in Computer Science and has worked as both a technical writer and programmer. Kathy Walrath is a senior technical writer on the Swing team at Sun Microsystems. After graduating from the University of California, Berkeley, with a B.S. in Electrical Engineering and Computer Science, Kathy wrote extensively about Unix, Mach, and NextStep. Since 1993, Kathy has been writing specifications and how-to guides for the Java platform.

Alison Huml is a technical writer at Sun Microsystems, where she joined The Java Tutorial team in 1997 and also works with the Security team. Alison received her B.A. in English from the University of California, Berkeley, and is currently pursuing her master's degree in Computer Science at Mills College.

Since the release of the Java Development Kit in May of 1995, the engineering team at Sun Microsystems has been hard at work improving and enhancing the Java platform. We have been similarly laboring to updateThe Java Tutorialto reflect the work of the engineers.From the first page to the last, this edition now documents the APIs in the Java 2 SDK, Standard Edition, v 1.3. We have fully integrated SDK 1.3 updates into the text, plus we've added questions and exercises to help you practice what you learn. To help beginners avoid many common mistakes, an entire chapter is devoted to programming problems and their solutions. Convenient summaries at the end of each section are also new to this edition.Like the first and second editions, this book is based on the online tutorial hosted at Sun Microsystem's Web site for the Java platform.http://java.sun.com/docs/books/tutorial/index.htmlLike the online version, this book reflects the latest advances in Java technology. Unlike the online version, this book solely focuses on the APIs needed by most beginning to intermediate programmers. Once you've mastered the material in this book, you can explore the rest of the Java platform on the Web site.Our intent has always been to create a fun, easy-to-read, task-oriented programmer's guide with lots of practical examples to help people learn to program. Who Should Read This Book?The book is geared towards both novice and experienced programmers. New programmerscan benefit most by reading the book from beginning to end, including the step by step instructions for compiling and running your first program in Getting Started (page 1). Programmers experienced with procedural languagessuch as C may wish start with the material on object-oriented concepts and features of the Java programming language. Experienced object programmersmay want to jump feet first into more advanced trails, such as those on applets, essential classes, or user interfaces.No matter what type of programmer you are, you can find a path through this book that fits your learning requirements. How to Use This BookThis book is designed so that you can either read it straight through or skip around from topic to topic. Whenever a topic is discussed in another place, you'll see a link to that place in the tutorial. Links are underlined and are followed by page numbers, like this: What Can Java Technology Do? (page 5).All the sample code used in this book is available online and on the accompanying CD. The CD icon in the margin indicates that the code is available. At the end of each chapter there is also a "Code Sample" section with a table that specifies the locations of the examples on the CD and online.We're dedicated to keeping this book up-to-date with the most current information.
