Using the diagram on pages 425&429, and the classes for this project, provided in the programming assignment, create a UML diagram of the Appointment hierarchy. The Appointment class is abstract,and all of its subclasses are concrete: Daily, Monthly, and Onetime. Note: Include all getters and setters for all attributes, even if the textbook doesn't have them. Also note, there is a polymorphic method in all the classes called occursOn(int year, int month, int day) that checks whether the appointment occurs on that date.. Also, italicize all abstract methods. To get FULL credit on UML and class hierarchy, make sure you use the optimal hierarchical structure, with the most general class on top, followed by a more specific subclass, and if applicable an even more specific subclass. Also, re-use the toString() methods in the superclasses, such that each toString() method adds a little more detail than what the super class had.
