java.util.Timer

if(e.getSource()==continuous)
{

    TimerTask task = new TimerTask()
    {
        public void run()
        {
            rollthedice();
        }
    };
    timer.schedule(task, java.util.Calendar.getInstance().getTime(), 500);


}

    if(e.getSource()==stop)
    {

        timer.cancel();

    }

i hit the continuous button, rollthedice() executes looping twice a second, i hit the stop button rollthedice() stops, what i been looking for is a way to hit the continuous button again after i hit stop to start looping the rollthedice() method again, the stop is to stop the continuous cycle of rollthedice() but i want to be able to hit the continuous button again, idk how to do it, i been looking and looking

Updated thoughts:

Runnable runner = new Runnable(){
    public void run()
    {
        rollthedice();
    }
}

if(e.getSource()==continuous)
{
  future = scheduler.scheduleAtFixedRate(runner, 0, 500, TimeUnit.MILLISECONDS);
}
if(e.getSource()==stop)
{

    future .cancel();

}

You could use ScheduledThreadPoolExecutor.scheduleAtFixedRate instead. This will allow you to submit a task, cancel it and then submit again.

From the javadoc for Timer.cancel():

Terminates this timer, discarding any currently scheduled tasks. Does not interfere with a currently executing task (if it exists). Once a timer has been terminated, its execution thread terminates gracefully, and no more tasks may be scheduled on it.

This means a new instance of Timer will be required to execute rollthedice() method again.
