how do i get a functon to repeat in java

Question

I am making a slapjack game where the deck will need to give to cards to the slapzone every 5 seconds and flip the image for 2 seconds before turning the picture back over. I know i will have to use a thread, but i can't figure out how to say repeat every 5 seconds i know the repeating part will take a for loop though.

Code:

public void run ()
{
    Thread thisThread = Thread.currentThread();     
    while (thisThread == myThread)         
    {
        try
        {
            for (int i = 0 ; i < numcards ; i++)
            {
                deck.giveslapZone(slap1); 
            }

            myThread = null;                // kills the thread 
        }
        catch (InterruptedException ie) 
        {
            System.out.println(ie.getMessage());    
        }
    }
}

Setting `myThread` to null does not 'kill the thread'. It exits the outer loop. They both appear quite pointless. — user207421, Jun 14 '15 at 03:29

you can make your class implements Runnable and then declare Thread thread = new Thread(this); and then: for eg.

public void run() {
    while(true) {
        try
        {
            for (int i = 0; i < numcards; i++)
            {
                deck.giveslapZone(slap1); 
            }
            thread.sleep(5000);
        }
        catch (InterruptedException ie) 
        {
            System.out.println(ie.getMessage());    
        }
    }
}

You can use ScheduledThreadPoolExecutor if you believe this may grow past a trivial implementation. A Scheduler thread would handle multiple threads and exceptions in a much smoother manner.

See the example in...

TimerTask vs Thread.sleep vs Handler postDelayed - most accurate to call function every N milliseconds?
