Is the Math class considered immutable?

[Bob Graffagnino]

I suppose objects are immutable, not classes. Since the Math class cannot be instantiated, the answers to my original question is - NO!

[Valentin Crettaz]

Immutability has to do with the state of an object. We say that an object is immutable when you cannot change its state after its creation (Wrapper classes, String,...). The Math class has no state, that is, it does not declare any members, except the two constants PI and E.
