Schedule a Task to Start After a Defined Interval

Imagine, you want to schedule activating a task few moments (3 seconds in this case) from now, and interval of 3 seconds. The following code will be helpful.

import java.util.*;
//We only need Timer and TimerTask from util package

public class ScheduleContinuous
{
   Timer scheduleTimer = new Timer();
   int defaultStartTime = 3000; //Seconds
   int defaultInterval = 3000; //Seconds
   
   public static void main(String args[])
   {
      ScheduleContinuous scheduleContinuous = new ScheduleContinuous();
      scheduleContinuous.proceed();
   }
   
   private void proceed()
   {
      //This will schedule the ScheduleContinuousTask to execute after 3 seconds
      scheduleTimer.schedule(new ScheduleContinuousTask(), defaultStartTime, defaultInterval);
   }
   
   class ScheduleContinuousTask extends TimerTask
   {
      public void run()
      {
         System.out.println("Start of Task");
         //Perform your task(s) here
         System.out.println("End of Task");
         //Add a condition to STOP
         //Invoke scheduleTimer.cancel() in the condition
      }
   }
}
