You have a collision. Collisions between interface methods can always be resolved providing the following three conditions apply:
  • 1: The methods have the same signature. (Otherwise it is overloading and not a collision at all).
  • 2: The methods have compatible intent (see below).
  • 3: The methods have the same return type. (You will have to check in the Java Language Specification for the exact details.)
  • You are violating no 3 here, and it will never compile.
    This is overloadingAnd this is incompatible intentObviously the WackyArithmetic#add method is only suitable for jokes, but I challenge you to implement both those interfaces in accordance with their specifications given.

    Have a look at these three add methods: note that the first is intentionally given a vague specification so both sub-interfaces can implement it differently, but still be compatible in intent. 1 2 3
