Static vs Non-Static Method in Java Static methods are utility methods in a class which can be exposed to other classes without having to create an instance of the owner class to call the method. Static methods can only be called directly (without using the class name) from within the class they are declared, whereas non-static methods can be called from other classes. Thus access to class's static fields is controlled by a lock that's distinct from the lock for any instance of the class.
