what I understand is that you have two text fields, when you are done entering text in one field, after a few seconds you want this value to be copied to the second field. — Amit Khanna, Dec 25 '12 at 07:17
yes @AmitKhanna but there is one more field where we can specify the time in secs,after the specified time the text should display in the other text field. — user1927762, Dec 25 '12 at 07:20

Check this

public class TimerExample extends JFrame {

    private JTextField textField1;
    private JTextField textField2;
    private JTextField textField3;
    private JButton btnSubmit ;
    private Timer timer;
    public TimerExample() {
        super("List");
    }

    public void createAndShowGUI() {

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new FlowLayout());
        textField1 = new JTextField(20) ; 
        textField2 = new JTextField(2) ; 
        textField3 = new JTextField(20) ; 
        btnSubmit = new JButton("Submit");
        add(textField1);
        add(textField2);
        add(btnSubmit);
        add(textField3);

        btnSubmit.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                int sec = Integer.parseInt(textField2.getText());
                 timer = new Timer(sec*1000, new ActionListener() {
                    @Override
                    public void actionPerformed(ActionEvent e) {
                        textField3.setText(textField1.getText());
                        timer.stop();
                    }
                });
                timer.start();
            }
        });
        pack();
        setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                TimerExample gui = new TimerExample();
                gui.createAndShowGUI();
            }

hey i accepted, am sorry that i just came to know that it should be done in javascript..any ways thanks for the correct answer..and i did the same in javascript. — user1927762, Dec 25 '12 at 09:47
The only problem is, if the user clicks the button more then once within the timers active period. Better to use a single instance of the timer and use Timer#isRunning - IMHO — MadProgrammer, Dec 25 '12 at 09:50

As you are working with gui I'm assuming you kow about threading.

So start a thread having run like this.

..run(){
..while(true){
..textbox1.setText(textbox2.getText());
..Thread.sleep(time interval);
..}
..}

time interval is in milisecond. for 1 sec write 1000.(remove the beginning dots)

Add a ChangeListener to the field1 from which you want to copy the text. Also keep a Timer property in the ChangeListner. On any change in the field1, stop the earlier timer if it is active, get the time from timeField and restart the timer.

ActionListener of timer can copy the value from field1 to field2.
