Online Resources for Java Programmers

The Web offers many resources to help you use the Java platform. This section lists some that we use ourselves, or that we've heard good things about.

Caveat: A Web site that's good one year might stagnate the next, and it can be difficult to tell unless you know the site well. Please tell us if any of these Web sites is obsolete, or if you have a URL for an excellent resource not mentioned here.

We list three kinds of resources:

General Programming Resources
Web sites that provide information useful to most developers.
Specialized Programming Resources
Sources of more specialized programming information. Examples include assorted tutorials, The Swing Connection, and a Web site for Macintosh programmers.
Other Resources
Other stuff, such as the latest industry news. Don't forget that our Tutorial has many examples, and that you can search all the java.sun.com tutorials(outside of the tutorial). Another source of resources is the Help section(outside of the tutorial) of java.sun.com.
