public class TimerDisplay extends JLabel implements ActionListener{
int count = 1000;
public TimerDisplay()
{
super("Remaining Time: 0 secs", JLabel.CENTER);
Timer t = new Timer(1000, this); t.start();
}
public void actionPerformed(ActionEvent e){
this.setText("Remaining Time: " + count++ + " secs");
}
public static void main (String arg[]){
JFrame f = new JFrame();
f.setSize(300,100);
f.addWindowListener (new WindowAdapter()
{ public void windowClosing(WindowEvent e){
System.exit(0);}});
TimerDisplay c = new TimerDisplay();
f.getContentPane()
.setLayout(new BorderLayout());
f.getContentPane()
.add(c, BorderLayout.CENTER);
f.show();
} }
You seem to have left elements out: where is this time of which you want to show how much is remaining?

I wanted to let the program countdown, for example 01 HR 30 MIN 30 SEC till 00 HR 00 MIN 00 SEC but i got no idea how to go about doing it.
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class TimerDisplay extends JLabel implements ActionListener{
int count = 1000;
public TimerDisplay()
{
// suppose to show as in 01 HR 30 MIN 30 SEC.
super("Remaining Time: 0 secs", JLabel.CENTER);
Timer t = new Timer(1000, this); t.start();
}
public void actionPerformed(ActionEvent e){
// suppose to countdown till OO HR 00 MIN 00 SEC
this.setText("Remaining Time: " + count++ + " secs");
}
public static void main (String arg[]){
JFrame f = new JFrame();
f.setSize(300,100);
f.addWindowListener (new WindowAdapter()
{ public void windowClosing(WindowEvent e){
System.exit(0);}});
TimerDisplay c = new TimerDisplay();
f.getContentPane()
.setLayout(new BorderLayout());
f.getContentPane()
.add(c, BorderLayout.CENTER);
f.show();
} }
