Making a clock that updates every second.

Question

I am at a loss and quitting for the night if anyone could help point me in the right direction I would appreciatte the advice. Here goes the code
import java.awt.*;
import java.awt.event.*;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import java.util.Date;
import java.util.Timer;
import java.util.TimerTask;
public class Clock
public static void main(String[] args)
TimerTask task = new DateTimer();
Timer timer = new Timer();
timer.schedule(task, 0, 1000);
JFrame frame = new JFrame();
JButton button = new JButton("Date & Time");
frame.add(button);
final JLabel label = new JLabel("Currently: ");
JPanel panel = new JPanel();
panel.add(button);
panel.add(label);
frame.add(panel);
class ClockViewer implements ActionListener
public void actionPerformed(ActionEvent event)
label.setText("Currently: " + task.getDate());
ActionListener listener = new ClockViewer();
button.addActionListener(listener);
frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
private static final int FRAME_WIDTH = 500;
private static final int FRAME_HEIGHT = 100;
import java.util.*;
public class DateTimer extends TimerTask
public void run()
Date now = new Date();
public Date getDate()
return now;
private final Date now;
Basically I am confused how to print the task out in the label.

Hi,
I have used [javax.swing.Timer|http://java.sun.com/javase/6/docs/api/index.html]
Hope this will be useful to you.
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Date;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.Timer;
public class Clock {
     public static void main(String[] args) {          
          JFrame frame = new JFrame();
          JButton button = new JButton("Date & Time");
          frame.add(button);
          final JLabel label = new JLabel("Currently: ");
          JPanel panel = new JPanel();
          panel.add(button);
          panel.add(label);
          frame.add(panel);
          ActionListener listener = new ActionListener()
               public void actionPerformed(ActionEvent ae)
                    new Timer(1000,this).start();
                    label.setText("Currently : " + new Date().toString());
          button.addActionListener(listener);
          frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setVisible(true);
     private static final int FRAME_WIDTH = 500;
     private static final int FRAME_HEIGHT = 100;
}Thanks
