    Post How to Use Timer in Java

    Hi everybody i did a small sample about using Timers in Java it's so simple to use.The main idea that you want to execute simple process every specific time.

    import java.util.Timer;
    import java.util.TimerTask;
     
    public class TimerSample {
     
        public static void main(String[] args) {
            //1- Taking an instance of Timer class.
            Timer timer = new Timer("Printer");
     
            //2- Taking an instance of class contains your repeated method.
            MyTask t = new MyTask();
     
     
            //TimerTask is a class implements Runnable interface so
            //You have to override run method with your certain code black
     
            //Second Parameter is the specified the Starting Time for your timer in
            //MilliSeconds or Date
     
            //Third Parameter is the specified the Period between consecutive
            //calling for the method.
     
            timer.schedule(t, 0, 2000);
     
     
        }
    }
     
    class MyTask extends TimerTask {
        //times member represent calling times.
        private int times = 0;
     
     
        public void run() {
            times++;
            if (times <= 5) {
                System.out.println("I'm alive...");
            } else {
                System.out.println("Timer stops now...");
     
                //Stop Timer.
                this.cancel();
            }
        }
    }

    I run this program on netbeans. it worked well except that it didn't end on itself. so I added System.exit(0); after this.cancel();
