Scheduling a Timer Task to Run at a Certain Time
============================================== 
 Date timeToRun = 
   new Date(System.currentTimeMillis()+
   numberOfMillisecondsInTheFuture);
 Timer timer = new Timer();
     
 timer.schedule(new TimerTask() {
         public void run() {
             // Task here
         }
     }, timeToRun);
============================================

Scheduling a Timer Task to Run Repeatedly

============================================= 
 // delay for 5 sec. 
 
 int delay = 5000;   
 
 
 // repeat every sec.
 
 int period = 1000;  
 Timer timer = new Timer();
     
 timer.scheduleAtFixedRate(new TimerTask() {
         public void run() {
             // Task here
         }
 }, delay, period);
