Java Examples in a Nutshell

Java Examples in a Nutshell has been relied on for years as a practical way to "jump in and try" new Java programming techniques and code. In this new edition, best-selling author David Flanagan has added coverage of regular expressions (new to the core Java API), extended I/O coverage, updated Java internationalization information, and extensive coverage of the new Java GUI features. For the strong of heart, he's also added some sneak peeks at some of the features that developers will see when the 1.5 version of Java releases late in 2004.

David Flanagan is a computer programmer who spends most of his time writing about JavaScript and Java. His books with O'Reilly include Java in a Nutshell, Java Examples in a Nutshell, Java Foundation Classes in a Nutshell, JavaScript: The Definitive Guide, and JavaScript Pocket Reference. David has a degree in computer science and engineering from the Massachusetts Institute of Technology. He lives with his wife and son in the U.S. Pacific Northwest bewteen the cities of Seattle, Washington and Vancouver, British Columbia. David has a simple website at http://www.davidflanagan.com.
