This is the reverse of the way a mathematician might look at it. From the point of view of mathematical set theory, Dalmatian has a superset of the methods of Dog.
I’d prefer to call them the less ambiguous base and extended / derived class, rather than super and sub class. To help you remember, "Mom makes super pie" — the mother original class is the superclass.
Another way to remember it is that the set of all Dalmatian objects is a subset (subclass) of the set of all Dog objects.
Yet another way to help you remember is the super keyword as in:
super.somemethod();lets you access Mom’s version of the method, so Mom, the class you were derived from, is the superclass.
Yet another way to help you remember is to think of a class tree dangling down from Object at the top. The superclass is above, the subclass below.
