The 1:java.util.timer class is a tool that a thread uses to schedule tasks to perform later in a background thread. You can schedule a task to execute once, or repeat it periodically.

The 2:timertask class is a task that is scheduled to be performed or performed repeatedly by a timer, because there is a timertask class that is an abstract class that must have its subclasses implemented to complete the scheduled task.

Timercallclient. Java Client code:

Timercallclient.java Code
  1. Package com.skyon.gd.test;
  2. Import Java.util.Timer;
  3. /**
  4. *
  5. * @author Sandy
  6. *
  7. */
  8. public class Timercallclient {
  9. public static void Main (string[] args) {
  10. Run ();
  11. }
  12. private static void run () {
  13. Timer timer = new timer ();
  14. Newtimertask timertask = new Newtimertask ();
  15. Execute tasks immediately after the program runs, every 100ms
  16. Timer.schedule (TimerTask, 0, 100);
  17. }
  18. }

Newtimertask.java Code:

Java code
  1. /**
  2. *
  3. */
  4. Package com.skyon.gd.test;
  5. Import Java.util.Random;
  6. Import Java.util.TimerTask;
  7. /**
  8. * @author Sandy
  9. * The TimerTask class is an abstract class
  10. */
  11. Public class Newtimertask extends TimerTask {
  12. @Override
  13. public Void Run () {
  14. Createrandomnumber ();
  15. Createrandomnumberfrommathrandom ();
  16. }
  17. //random number between 1-10 randomly generated using the method in pure math
  18. private void Createrandomnumberfrommathrandom () {
  19. int j= (int) (Math.Round (Math.random () *+1));
  20. System.out.println ("Randomly generated numbers are:" +j);
  21. }
  22. //randomly generate random numbers between 1-10 in random class mode
  23. private void Createrandomnumber () {
  24. Random random=New Random (System.currenttimemillis ());
  25. int value=random.nextint ();
  26. Value=math.abs (value);
  27. value=value%1;
  28. System.out.println ("The newly generated number is:" +value);
  29. }
  30. }
