Sandeep,
Interface B gets the compilation error saying, "The return
type is incompatible with A.test()"
Hence, the proposed solution is not correct.

Answer / kssrk ramesh
forget about implementing the interface
First of all can we can not have two similar method names
only with return type as different.As per overloaded method
concept it is not acceptable.So inorder to implement the
interfaces we need to do like that which is not acceptable
as per overloaded methods principle and hence compilation
error.

Answer / nitin
Ramesh,
I am agree with the technical boudries which you have
talked about. But this is a real problem and have to cope
with it.
We can not change the interfaces at all, but there should
be a way to achieve the goal, may be using inner class or
so.
