java - How pause and then resume a thread?

Question

I state that I read about thread, but I've never used. So I ask to you :)

I have two thread: A and B, where A manages the GUI, and B manages the logic.

I would start with A.

Then when A draw the GUI, I would pause it, to wait B that reach a point X into run method.

And when B reach the X point into run method, I pause B, and resume A.

A and B share some variable to manage the GUI, and the logic...

Can I do it? if yes, how? :)

Answer 1

Using wait() and notify() methods:

wait() - Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object.

notify() - Wakes up a single thread that is waiting on this object's monitor.
