      }
   }

   public static void main(String args[]) {
      CountThread thread1 = new CountThread(0,100);     //You may want to tweak the ranges
      CountThread thread2 = new CountThread(1000,1100); //For these two instances
      
      thread1.start(); //Start up the first thread
      thread2.start(); //Start up the second thread.
   }
