I got a request from someone that asked me to create an applet that can be used as a quiz, well since I had a bit of time today I went ahead and coded it for him. The questions will be randomized every time you run the applet but as of now I’ve only made 5 questions so the application picks the first 5 questions available. I’ll see if I can upload a demo somewhere to show you how it works but the applet needs a java.policy file that doesn’t run in a browser so i’ll see if i can manage to create a self signed java applet.

Someone asked me to write an application that:

• Use an array to store the data for the different brands.
• Must have 4 additional index positions available for data entry so that I may be able to add
• Must ensure that PR or Plain Wrap is not duplicated in data entry
• Cannot use scanner
• You may choose to use 2 dimensional array (one class needed) or object of array(two classes needed)

Output:
• You will need to display the plain wrap number chosen and the corresponding Brands for that particular part.

So here it is:

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");
  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. }
