Introduction

3. How do I make a thread?

   class Foo extends applet
   {
      Bar b = new Bar();
   
      public void init()
      {
         ...
         b.start();  // Get the thread going.
         ...
      }
   }
   
   class Bar extends Thread
   {
      ...
   
      public void run()
      {
         // This is where the thread "lives."
      }
   

   Other thread methods:
   1. sleep()
   2. start()
   3. stop() -- deprecated.
