If I have a static synchronized method, can I never release the lock till i finish the method?
Yes, unless you call wait() (see below), which releases the lock. Of course, you could use a synchronized block within the method which has the same effect as declaring the method synchronized - except that you can control when it starts and ends:
I used the MyClass.class object as the monitor, because that's what the monitor would have been if you'd used a static synchronized method (assuming it's in the class MyClass).
Because , wait and notify cannot be used in a static method...
They can, if you use an object to call them. I.e. you can't use just plain wait() since that means this.wait() and there's no "this" in a static method. But you can call someOtherObject.wait(). Inside a static synchronized method, you could release the lock with
