Question

In my main program I am running 1 User Thread and all its child are daemon threads. Because of this when the user thread finished its working all daemon threads terminates as well. I am executing some code block in daemon threads that must be finished before thread termination.

Is it possible to wait for a particular block execution in daemon thread if user threads finished their working?

Answer 1

You can implement this different ways

1. Using Thread.join();
2. Using Observer-Observable pattern
3. Using CountDownLatch
