doubt - innerclasses & interface

[Naresh Gunda]

Hi Friends,
Which of the following statements is true?

a) An interface can contain a nested top-level inner class.

b) An interface can contain a member inner class.

c) A member inner class can implement an interface.

d) A static method can contain a local class.

e) A static method can contain a nested top-level class.

I didn't understand options a& e
can you please give me some sample code to represent the options a & e.
Thanx & Regards
Naresh

Hi,

An interface can contain only nested top level class that means static member class.

So option 'A' is wrong. If they mention it as nested top level class instead of nested top level inner class then it would be correct.

Option 'E' is wrong because a static method can contain a local class or anonymous class not a nested top level class.

Please correct me if i'm wrong.

Surekha.
