So you have a adress class that implements the adress interface. You would create an AdressImpl object inside the person class or you can inside the main method. I can not remember the exercise and that is why I asked for more information.
Just remember that you need to create an AdressImpl object somewhere. Now I am sure the exercise might say what to do. You could create the object within a peron constructor or even a method.
