threads -- start order

[H. Ali]

is it possible that t2 starts before t1 even thought we have :
t1.start();
t2.start();
does it have to be in the same order???

The Java specification doesn't impose any order. It is dependent on the underlying operating system's threading mechanism.

Having said that, how do you define "start order"? Even if the specification impose an order, how can you tell? It is completely possible for t1 to "start" first, and t2 to "start" second"... but t1 gets scheduled on a processor that immediate takes a hardware interrupt.
