Thread in Thread

[Drew Lane]

Say I have two threads, A & B.

Thread A is started from the main event thread.

Thread B is started inside Thread A at the very end of its run method.

Does thread A stay alive until thread B is finished?

[Mike Simmons]

No. Not unless you put something else in A to keep it alive. But if starting B was the very last thing in A's run() method, then there's no reason for A to stay alive after that.

[Peter Lawrey]

No. If the last thing A does is create B, there actually there is no point creating B, just use A to run what B would do.

[Angel Taveras]

It could stay alive, but it's uncertain the behavior of these two threads. If you want that Thread A remain alive while Thread B it's running the you have to join them with Thread.join.
