Newly revised for some of the latest Sun JDK 1.3 standards, the second edition of Sams Teach Yourself Java 2 in 21 Days provides a refreshingly compact and useful tour of Java suitable for anyone who wants to master this powerful programming language quickly.

Currently, Java has some 2,000 classes and over 24,000 methods and properties. Instead of covering a laundry list of features, this book concentrates on what's really important, and keeps your attention with short, clever examples, many of which use names and examples drawn from pop culture or historical trivia.

The first week of lessons in the book comprises an easily digestible tutorial on basic Java, with review questions and exercises that will help you start using it on your own. Next comes a tour of the various options for building user interfaces in today's Java, including Swing applets and applications. In addition to basic component programming, you'll learn graphics using the new Java 2D API. (The older Abstract Windowing Toolkit, AWT, isn't covered.) Material on threading, animation, and sound helps you explore Java's multimedia capabilities.

The third and final week of lessons addresses advanced Java APIs and features that extend the reach of Java on the enterprise. After delving into more advanced class design, the book looks at topics like I/O streams in Java and Object Serialization (which allows objects to work with streams). Chapters on security and basic networking (illustrated using a server that generates trivia questions for clients) will let you work with Java on the Internet. The book closes with a chapter on database programming with JDBC. (There's also coverage of the older JDK 1.0 collection classes, which is a little surprising given the book's focus on newer Java 2 standards.)

All in all, Sams Teach Yourself Java 2 in 21 Days provides an efficiently packaged tutorial for learning Java, one that will be appreciated by any beginning Java programmer. The sheer number of classes and APIs in today's Java can be overwhelming. The intelligent and concise series of lessons in this book will help jump-start your knowledge. --Richard Dragan
