Hogwarts:
This class is a subclass to School. Its purpose is to serve as the school of Hogwarts and provide methods that are specific to the fictional school. For example there is a method that tells you whether a student or teacher is part of Dumbledore's Army and a method that can tell you who is the wisest wizard at school based on their age. This class also implements the interface Enrollment which provides a method that relates to enrolling in the school of Hogwarts. For more information about the different methods in this class, refer to the comments made in my code.
