Generally the methods which operates on locks accepts timeout as an argument. If you are using wait(), you can specify the amount of time by passing time to wait as argument. Check here for more details: http://docs.oracle.com/javase/7/docs/api/java/lang/Object.html#wait%28long%29.

If you are using Lock, then try tryLock method of it which accepts time it has to wait. Check this tutorial for an idea: http://docs.oracle.com/javase/tutorial/essential/concurrency/newlocks.html
