Thread problems

Hi:I have coded a class A which starts a new thread when it is called.Also I get a class B in which I call A for several times.My question is how do I in class B know the end of all threads which started by me? Is there some APIs that inform me?Thanks.

By calling join.

That's the simplest way, if you only need to know when all threads are done. If you want to know as soon as each one is done, without having to worry about the order or waiting till they're all done, then when each thread finishes, it will have to call some method on some shared object that the main thread can observe.

Also, do you want to block until those threads are done, or do youwant to be asynchronously notified when the last thread is done?
