Question

I want to write a method that gets 2 parameters:

1. an interface.
2. a class that implements that interface.

I want it to be generic (compile time type safe).

is there a way?
if not, whats the alternative?

is there an option to get generic param that is an interface? ho do I declare it?
?

Answer 1

some thing like this ??

public <I, K extends I> void method(I i, K k){

    }

In the above method first parameter would be an interface, and second parameter would be any class that implements that interface.

    Interface1 i1;
    method(i1, class1); //class1 implements Interface1

In generics, interface implementation and class extending is represented using extends keyword. there is no implements keyword in the world of generics.
