Suppose i synchronize a instance method in a class and create two objects A and B of the same class. Now when object A is accessing the synchronized method will B also be able to access it or will it have to wait until A releases the lock?

They lock different objects (the instance in question), so the methods will be able to run at the same time.

If you synchronized a static method, that locks the class object, and so then any call can block any other.

Thanks Matthew.
 
Arch enemy? I mean, I don't like you, but I don't think you qualify as "arch enemy". Here, try this tiny ad:
