Hi Friends,
I am trying to implement concurrence processing in java by threads.
From a main process I want to start 2 child processes. Then main process has to wait until all of its child processes got completed. Here 2 child processes can run parallel.
So how can I stop main thread until all children execution get completed.
Thanks in advance,
Yamini.

Use the "join()" method. Call it on each thread that you want to wait for, one after the other. You won't get past the last call until all the child threads have completed.
