There will be an intermediary class which will have composition relationship with our interface. Abstract Factory specializes in creating families of related objects. Another difference between factory pattern and abstract factory pattern is that the factory pattern hides the construction of a single object while abstract factory pattern hides the construction of a family of related objects.
