Conflicting interface methods in Java [duplicate]

Answer 1

You can write an Adapter class to implement one of the interfaces.

Example implementation:

class AdapterA implements A{
     AdapterA(C c){impl = c;}
     private final C impl;
     public int foo(){return c.fooReturningInt();}
}
class C implements B{

   public double foo(){...}
   public int fooReturningInt(){...}
}
