running background thread continiously...

ok..my aim is to run 2 threads concurrently...let s have a lokk at the following code....

import java.io.*;

import java.util.*;

class testtimer extends TimerTask

{

public void run()

{

System.out.println("timer started");

}

}

class testtimer2 extends TimerTask

{

public void run()

{

System.out.println("timer 2 started");

}

}

class maintimer

{

public static void main(String args[])

{

testtimer t1=new testtimer();

testtimer2 t2=new testtimer2();

Timer tm=new Timer(true);

tm.schedule(t1,1000,1000);

tm.schedule(t2,1500,500);

try

{

Thread.sleep(10000);

}

catch(Exception e)

{

System.out.println("Exception occurred");

}

}

}

now suppose i want to run this program till to computer shutdown....

and i also want to fix the execution time of both the timertask thread..
