I Think these are the answers . Pls Correct me if I am Wrong .

1)An interface definition is limited to having only final Variables and Method Signatures.

2)A concrete class cannot have abstract keyword or abstract method declared in its definition.

3)A Private/ Final class cannot have any subclasses.

4) The keyword to denote inheritance of implementation is extends.
