Can someone tell me what I am doing wrong here? The program seems to execute eternally(and does not print DONE) though I am changing the condition of the boolean variable in the thread. Basically, I want the main thread to resume once a condition is satisfied in the thread. How do I achieve that?
First of all you must signal the resumed thread with condition.signal().
You remember about very important lock.unlock(s) in finally sections.

Thanks a lot, Adam!! Currently, there is no way to get the list of all available conditions on a particular lock, right? I just see this API -
Condition c = lock.newCondition();
So, if I want to split the above mentioned code in different classes ( the sleep thread in one class, and the variable monitoring code in another class), I shall need to pass the references to both lock and the condition the first class created, right?

Essentially, I personally would NOT make access locks and conditions outside class without very justified reason.
Next, I would browse existing solutions in java.util.concurrent package like Executors, CyclicBarrier etc..
In case of need, you consider my somewhat other approach to your described problem(semantically should be equivalent):
var = false
var = true
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
