Threads are tricky! You start them easily.. but how do you stop them. Consider this example (it works more or the less) but each time I test the pedal a new thread is started.... so what are all these started threats doing:

Code:

class PedaltestThread extends Thread {
        private int cnt;  // The name of this thread.
        public PedaltestThread(int cnt) {  // the thread counter
        this.cnt = cnt;
        }
            public void run() {  
                midipedalflag=false;  // the flag set by midipedal
                do  {                 // and space bar
                       
                } while (!midipedalflag);
                midipedalflag=false;
                midipedalTest.setSelected(false);
                System.out.println(" pedal pushed " + cnt);
            }
 }


 private class EventHandler implements  ActionListener {
        
         public void actionPerformed(ActionEvent evt) {
           Object source = evt.getSource();
 
           if (source ==  midipedalTest)  {
               
                if (midipedalTest.isSelected()) {
                   
                   threadcount++; // thread counter
                   pedtest  = new PedaltestThread(threadcount);
                   pedtest.start();
                   
                    
                }
                if (!midipedalTest.isSelected()) {
               
                }
        
           }
