Hi,

I have two different thread.
One for getting data from database, another for getting data from file system.
These two thread are independent of each other.
Once both get completed, need to send mail which contains fetched data from database and filsystem as well.

function call is as follows:



Now how to make sure that mail will be send only when both thread (thread1 and thread2) will be finished?

Thanks,
Ranu.

Right before sendEmail(), call

thread1.join();
thread2.join();

and that's it!
