How can you tell if threads are done?

Check Thread. isAlive() in a polling fashion — generally discouraged — to wait until each Thread has completed, or.

What is wait () and notify () in multithreading?

The wait() method causes the current thread to wait until another thread invokes the notify() or notifyAll() methods for that object.
