What's New in This Edition? This second edition covers the latest developments in the Java 2 Standard Edition SDK 1.3 and 1.4. We've tried to highlight the changes from 1.2 in case you have to work with older releases for compatibility or political reasons. For brevity's sake, we refer to Java versions by their SDK version number, describing this or that feature as having been introduced in SDK 1.3 or 1.4. Earlier versions were called Java Development Kits, so in those cases we refer to JDK 1.1 or 1.2. This new edition incorporated your feedback from the first edition! The first edition was too heavy on the documentation side for many readers. The Javadoc for the Swing packages continues to improve, and more and more people are familiar with the patterns of Java classes and methods. With those two facts in mind, we try to focus on the parts of the API that are interesting and useful rather than just including them because they exist. We added many new examples and improved the existing examples. This book is a true and thorough revision of the first edition, not a mere update. As a quick reference to some of the changes you'll find in the 1.3 and 1.4 releases of the SDK, Table P-1 and Table P-2 list any significant changes to components and briefly describe those changes. We detail these changes throughout the book as we discuss the particular components. Table P-1.
