Problem
Draw and create a UML Diagram that shows the four classes and their relationships: PERSON, ATHLETE, COACH and REFEREE. There's a parent class PERSON, which has three subclasses, those are ALTHLETE, COACH and REFEREE. All of them may have different methods, attributes or both. Lets consider carefully which methods and attributes belong in PERSON- they apply to everyone at the Olympics- and which only apply to some people at the Olympics and also belong in subclasses. Mention one attribute and one method.
