Hi Friends,
The obvious ans. to the code is 2 but I fail to understand why option 4 is wrong?
What is the effect of issuing a wait() method on an object
1. If a notify() method has already been sent to that object then it has no effect
2. The object issuing the call to wait() will halt until another object sends a notify() or notifyAll() method
3. An exception will be raised
4. The object issuing the call to wait() will be automatically synchronized with any other objects using the receiving object.
Thanks

I think 4 is just worded so that it sounds like a good answer. wait() realy doesn't have anthig to do wiht synchronized objects specifically (you can call wait on any thread, regarless of wehter or not its in synchronized code). It's just that usually wait is used within the synchronized code to control access. when you call wait on a thread it just stops and waits. It doesn't do anything else. If it was in synchronozed code it'll release the lock on the monitor but it doesn't do anything to or with any other objects.

If I'm wrong on anything here someone please corect me.
