Is there any difference between Immutable objects and classes? according to my understanding from mock tests Math is an immutable class. objects of Double, Integer etc., are immutable objects.

According to my understanding Math Class is final class so it can not be subclassed or extended. Objects of Doubl,Integer Etc. (Wrapper Classes) are immutable objects so their objects can not be changed.

Is it possible to change the state of a class? I do not think so. Math is a utility class: uninstantiable and full of static useful methods. A immutable class should produce immutable instances.
