Answer / gohil

You can dynamically implement any of the interface
Ex
a intAImpObj= new ab();
b intBImpObj= new ab();

In above case intAImpObj is the implementation of a
interface and intBImpObj is the implementation of b interface

Answer / narayana

There should be no confusion. Since both the interfaces are
been implemented and both have the same method signature and
return type, it will
work fine and will take any of the method.
Since there is no implementation in Interfaces it is
difficult to know which interface the method is read.

I have a sorting issue with a Hashmap. My constraint is that I MUST use the Hashmap and work with existing code. I do a database query and place the results in a Hashmap. When I iterate thru the Hashmap, it loses the original alphabetical sorting done by the database. So, my problem is that I must sort the results coming out of the Hashmap which is then placed into another class.
