Answer #1

Use Multithreading in JAVA.

When you call AddCook(); in the Restaurant thread, it will wait(). And then nothing will happen anymore. The problem is, that you have only one thread, this one cannot notify itself. I think what you want to do is turn your Client, Waiter, and Chef into threads. Then start them one after another and then the Waiter has to wait until the Client made his order and the Chef has to wait until the Waiter got the order...

This is like "java producer-consumer example".
