How to create a timer function by only using Threads

Question

I have used Timer & Timer Task but since they r only available for JDK1.3 and i need this to work on 1.2 also can any one tell me if i can create the same function using Threads.

Answer 1

i had to do the same (heres roughly what i used...)
interface TimerTask{
public void timeout();
class Timer extends Thread{
private int delay;
private TimerTask user;
Timer(int delay,TimerTask user){
  this.delay=delay;
  this.user=user;
public void run(){
  try{
   Thread.sleep(delay);            //*
  catch(InteruptedException IE){};
  user.timeout();                  //*
}as you can see, very rough, but the basics
refinements could be to add some flags to alter its behaviour..
like, a loop if you want recuring events
the commented lines might be rearranged if you dont want it to generate an event just because there is some shut down going on
as it is an instance of a class could only use 1 Timer, to change this TimerTask.timeout() could be changed to TimerTask.timeout(Timer) so you could determine which Timer had triggered
