I think the application will terminate and a stack trace will be printed on the screen.

Your application may or may not terminate. Whenever there is an uncaught exception in a thread, that thread dies. Ofcourse if your program has only 1 non-daemon thread, i.e. user-thread (for eg. only a main thread), then JVM will exit. Otherwise if there are multiple daemon threads running, then the other threads will happily continue to run and JVM will not exit.

i agree with u Junaid
Noel try this code and u will get the answer
public class A extends Thread{
static int i=0;
public void run()
{
System.out.println("all done before"+i);
if (i ==0)
i = 1/i;
System.out.println("all done"+i);
}
public static void main(String[] args){
A t1 = new A();
t1.start();
try{
sleep(200);}catch (Exception e){}
i++;
A t2 = new A();
t2.start();
System.out.println("all done. exiting now");
}
}
