Thread Priority issue

[saikrishna cinux]

public class Test implements Runnable{
static Thread t1;
static Thread t2;
public static void main(String args[])
{
Test t=new Test();
t1=new Thread (t);
t2=new Thread (t);

t1.setPriority(1);
t2.setPriority(10);
t1.start();
t2.start();
 
}
public void run()
{
System.out.println(t1);
System.out.println(t2);
 
}
}

here i am setting thread priority to 2 threads max priority to second thread and min proprity to 1st thread but the 2nd thread is not running first

why?

If i remember correctly using thread priorites is at the discretion of the OS.

Consider using your own thread scheduler.

As your run() method does so little, one could not reasonably expect priority to have much effect. In fact, t1 may have started and finished, before the t2.start() statement even runs.

As previous poster has pointed out, Java makes few promises about exactly what thread priorities will do. This is to accommodate different platforms. In practice, however, JVMs on major OSs will respect priorities reasonably well. But, to see it, you'd need to give the threads worthwhile work to do: something that takes a few seconds (and don't use sleep(), wait() etc. because that's not work).
