/* Scheduler Task :

 * How to run a task periodically in Java

To execute a method between a regular interval of time.*/

class ScheduledTask extends TimerTask {

     Date now; // to display current time

     // Add your task here

     public void run() {

          now = new Date(); // initialize date

          System.out.println("Time is :" + now);

     }

}

// Run Scheduled task

public class TimerApp {

     public static void main(String[] args) {

          Timer timer=new Timer();

          ScheduledTask sTask= new ScheduledTask();

          timer.schedule(sTask, 0, 2000);

     }

}

Output :

Time is :Tue Mar 08 00:11:15 IST 2016

Time is :Tue Mar 08 00:11:17 IST 2016

Time is :Tue Mar 08 00:11:19 IST 2016

Time is :Tue Mar 08 00:11:21 IST 2016

It keeps running until it comes with a terminate condition like System.exit(0)
