The School of Hard Docs

If you haven't already, you'll probably want to download the Java API Documentation and bookmark it in your favorite browser (I.E. IE). The API documentation is an HTML reference with complete method and class listings of all classes in all packages of the core API. It's an invaluable reference that I've already referred to twice today.

When you can't remember if JCheckBox's constructor takes the String argument first, or the boolean argument, you turn to the docs.

(What does it say about the prevailance of Java when the first hit in Google for "String", a fairly common word, is the Java API doc page?)
