Nested classes without parentheses?

[available]

@dalewking

In what context? Would never make sense to put parentheses after an interface as you cannot create an instance of one. It would make sense to use parentheses when subclassing the abstract class but that is the only place as in:

Actually I was ask that why not used the parantheses on ViewSwitcher.ViewFactory or RecyclerView.Adapter. Maybe I understood wrong. I need the paranthese when I do try like the example. Why not used the parantheses in this code?
