Brewing Java: A Tutorial

Comments you might have on the structure, organization or contents of this document are appreciated. Although a lot remains to be fleshed out, the basic structure is as follows:

Part 1 is a brief introduction to what Java is, why it’s cool and what you need to use it.

Part 2 is a tutorial introduction to Java that just covers what you need to know to start programming command line applications in Java. This is an introduction to the basic syntax of the language. It skims over many details and completely omits little used features like bit-shift operators. This section is fairly complete.

Part 3 covers the basics of writing applets in Java.

Part 4 introduces you to objects and classes.
