Here's a demo I wrote to show an example of the usage of a timertask. This demo will show a "reminder" dialog after x seconds.

PLAIN TEXT

JAVA:

1. public class TimerTaskDemoV2 extends JDialog  implements ActionListener {
2. Timer timer;
3. JTextArea info = new JTextArea("This is a reminder..\nBy: HappyFace\nwww.engineeringserver.com");
4. JButton ok;
5. public TimerTaskDemoV2(int seconds) {
6. timer = new Timer();
7. timer.schedule(new RemindTask(), seconds*1000);
8. }
9. public TimerTaskDemoV2(){
10. getContentPane().setLayout(null);
11. info.setEditable(false);
12. info.setBounds(0,0,200,100);
13. ok = new JButton("Close");
14. ok.addActionListener(this);
15. ok.setBounds(0,100,200,30);
16. add(info);
17. add(ok);
18. setTitle("Reminder");
19. setDefaultCloseOperation(0);
20. setSize(207,155);
21. setResizable(false);
22. setLocationRelativeTo(null);
23. setVisible(true);
24. }
25. class RemindTask extends TimerTask {
26. public void run() {
27. TimerTaskDemoV2 tmp = new  TimerTaskDemoV2();
28. timer.cancel();
29. }
30. }
31. public void actionPerformed(ActionEvent e) {
32. if(e.getSource() == ok){
33. System.exit(0);
34. }
35. }
36. public static void main(String args[]) {
37. int wait = 5;
38. System.out.println("Wait "+ wait + " second(s)");
39. new TimerTaskDemoV2(wait);
40. }
41. }
