Hi there :)

AFAIK inner classes are like normal classes except with the name
mangling.
Private inner classes are private to that class (similar to un-nested
top level private classes in the same .java file).  Other inner classes
are theoretically public but the compiler ensures that they can't be
constructed from outside the outer class (or specialized versions of the
outer class).
