Inner classes has an automatic access to the members of the enclosing
class (outer object). To do that, inner classes stores a reference to the
particular object.

If we don't need the connection between the inner class object and the
outer class object, then we can make the inner class "static". And this is
commonly called "nested class".

Also a nested class means:

1. We don't need an outer-class object to create an object of the nested
class.

2. We cannot access a non-static outer-class object from an object of a
nested class.

Hope this helps.
