Question

I have two Class A, B.

For A, I have two method callB(), and checksomethinginB().

For B, I have one method execute().

I use them like:

A _a;
_a.callB(); //inside the function, B object _b will be created

//after _b created, in another place, _b will execute _b.execute().
_b.execute()
{
   // I want to use A method checksomethinginB()
}

So I don’t know a good way to use A method in B, what I can create is to use static functions, but I think there maybe better way, thanks for your suggestion!!

Answer 1

Either pass the correct instance of A to the constructor of B, or pass it along whenever needed.

If checksomethinginB doesn’t need any state in A then it can be static of course.
