Does it make sense to have a count of "heads" in one instance of the Head class? If an individual could have more than one head, then it should be the Person class (or similar) that knows it, not the Head class. Also, all "body parts" could derive from a common superclass BodyPart that could factor out common code.

I concur with both the changes. This requires creating a list of body parts maintained in "person". Also, using "setters" for each body part to add additional instances of body parts to the respective list. |
