What does it mean if a class is declared as static?

Question

I know that variables in a class declared as static is to be shared by all instances of that class, but what does it mean when a class is declared as static?

Answer 1

imagine a nested classes.

class Outer{
class Inner { }
}

in this case you'll need an instance of Outer to create an instane of Inner.

new Outer().new Inner()

looks ugly right ? if you declare Inner as static you'll only need the Class just like a static method/variable

new Outer.Inner()

Answer 2

Taste Ah I see, that makes me more enlightened now. Thank you, very appreciated.
