Garbage collection of threads

Question

1. class MyThread extends Thread {
2. public void run () {
3. longTermJob();
4. }
5.
6. public static void longTermJob () {
7. for (int i = 0; i < 10000; ++i) {
8. System.out.println(i);
9. try {Thread.sleep(1000);}
10. catch (InterruptedException) {}
11. }
12.
13. }
14.
15. }
16.
17. class Test {
18. public static void main (String[] args) {
19. new MyThread().start();
20. MyThread.longTermJob();
21. }
22. }
After execution in line 19, the object of MyThread
is not referenced by any variables; and hence
could be destroyed by garbage collection thread.
My question is :
When the garbage collection is started and
detects that the object(MyThread) is no longer
referenced by anyone and the thread created by
MyThread object is still in execution, would
the thread finish successfully or
stop abnormally?

My question is :

MyThread object is still in execution, would
the thread finish successfully or
stop abnormally?Unless the VM is exited, it will run normally until is finishes. Then if there are no more references to the thread, it will be garbage collected eventually.
