Several chapters here are especially useful for getting control of new and important Java 2 features. Sections on the new Java 2 collection classes and using advanced Swing classes (like tables and trees) are particularly good. (While many other books just list Swing APIs, this volume provides short examples and effective commentary, which will let you master these complex Swing controls.) When it comes to Java2D graphics, the authors do a nice job of comparing the old AWT to the new Java2D, including drawing basic shapes and doing text output. (These operations are surprisingly tricky in this new API). A section on the new JDBC 2 standard shows off new features like ResultSets and scrollable cursors to good effect.
More advanced topics include multithreading, internationalization, and security. Throughout, this text introduces important concepts illustrated with comprehensible examples. The APIs for individual classes are listed too, making it possible to use this book as a reference, but it is the tutorial sections that stand out here. (The authors also aren't afraid to point out where Java 2 is lacking--for example, in its printing support.)
Readers of the first volume will naturally want the second volume of Core Java 2 too. It's also a great choice for any Java developer with JDK 1.1 experience who wants a tour of new Java 2 features that are essential for serious corporate development. --Richard Dragan
