Conventions Used in This Book

This book uses various typefaces:

• A special monospace font is used to help you distinguish code-related terms from regular English, for. Here's an example: The actionPerformed method handles menu selections, setting the appropriate drawing flags as needed.

• As I develop the code in this book, the new code being added will appear this way:

   import java.awt.*; import java.awt.event.*; public class Intercom1 extends Frame implements Runnable, ActionListener {     public static void main(String[] args)     {         new Intercom1();     }     .     .     . } 

  
  

• Each chapter has a real-world scenario, which looks like this:

  REAL-WORLD SCENARIO

  You're going to find real-world experience and insights in real-world scenarios like this one. These track what's going on in the computer industry, in the technology under discussion, or just generally in programmer's lives these days.

  
  

• Notes, tips, and cautions look like this:

NOTE

Notes provide additional information related to the surrounding topics.

TIP

Tips provide shortcuts to make a task or better ways to accomplish certain features.

CAUTION

Cautions alert you to potential problems, or to common pitfalls you should avoid.

And that's all you need. Get ready and turn to Chapter 1, "Making Fish Swim in the Multithreaded Aquarium," to crank things up and make those fish swim.
