Thread Objects:

new Thread(aRunnableObj ).start();

1. The most commonly used constructor in class Thread accepts a Runnable object as an argument, which arranges to invoke the Runnable's run method when the thread is started.

2. Whle any class can implement Runnable, it often turns out to be both convenient and helpful to define a Runnable as an anonymous inner class.

eg :

public Thread makeThread( Particle p) {

   Runnable runloop = new Runnable() {
      public void run() {
         try {
             while (true) {
                  p.move();
                    canvasPanel.repaint();
                    Thread.sleep(100);
              }    // while
         }      //  try
         catch( InterruptedExceprion ex)
          {
               return;
          } 
      }    
   };       // anonymous inner class  
   return new Thread(runloop);
}
