A timer Function

effectivly I want a function that does this:

import java.util.Timer;
import java.util.TimerTask;

/**
 * Simple demo that uses java.util.Timer to schedule a task to execute
 * once 5 seconds have passed.
 */
public class autoTimer {
    public static void main(String[] args) throws Exception {
        autoTimer t = new autoTimer();
        t.execute();
    } private void execute() throws Exception {
        System.out.println(" Tasks scheduled");
        int initialDelay = 1000; // start after 30 seconds
        int period = 2000; // repeat every 5 seconds
        Timer timer = new Timer();
        System.out.println(" Timer set");
       
        timer.scheduleAtFixedRate(new TimerTask() {
            public void run() {
                System.out.println("Task Run");
            }
        } , initialDelay, period);
    }
}

I don't have much to contribute but
Have you looked at these?

just to clarify, put all this code in 1 file -  ScheduleTask.java

Use a servlet that uses the code you posted above to run your task. And have that servlet load on startup.

I have implemented the load on start up and i found out that I was not using the full class path, so that is fixed.

Say I want this timer to wake up based on a list of times I give it, so for example.

I have a Vector of objects passes, with startTimes which are number of secs since epoch.
how would I go about creating a function that will wake up to preform a task, based on a list of objects.

Use the Timer task to schedule the first time to perform task from your Vector, when this task is executed and completed then schedule the next time from Vector for task to be completed.
Repeat this until done.

how would I do that, if possible could provide code skeleton.
