Why static inner class?

Can someone explain why we need a static inner class ?

The answer I could find is that static inner classes can not access the parent class' non-static field variables and methods.

Hi Kristian,

There is no such thing as a static inner class; per Java's own documentation, "Nested classes are divided into two categories: static and non-static. Nested classes that are declared static are called static nested classes. Non-static nested classes are called inner classes."
