Could you be a bit more specific? What do you mean with communication?

If you have two classes A and B you can call a method of A from a method of B if either an Object of class A is a member of B or there is an Object of class A inside the method of B:

B::SomeMethodOfB()
{
     A objA;
     objA.SomeMethodOfA();
}
