How do I create a scheduled task using timer in java?

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;

public class TimerExample extends TimerTask {
        private DateFormat formatter = new SimpleDateFormat("hh:mm:ss a");
        
        public static void main(String[] args) {
                // 
                // Create an instance of TimerTask implementor.
                //
                TimerTask task = new TimerExample();
                
                //
                // Create a new timer to schedule the TimerExample instance at a 
                // periodic time every 1000 milliseconds and start it immediately
                //
                Timer timer = new Timer();
                timer.scheduleAtFixedRate(task, new Date(), 1000);
        }
        
        /**
         * This method is the implementation of a contract defined in the TimerTask
         * class. This in the entry point of the task execution.
         */
        public void run() {
                //
                // To make the example simple we just print the current time.
                //                              
                System.out.println(formatter.format(new Date()));
        }
 }
