Question

Create class Course as per its UML diagram. Then, create subclasses Faculty and Student that extend class Person from the Chapter 9 Assignment (just copy-paste it from our Chapter 9 assignment). Refer to the UML diagrams to give these classes attributes and methods. Do NOT add any attributes or methods that don't appear in the UML diagrams. Create an executable class named TestCollege to test your work. In TestCollege, add code that accomplishes the tasks below. The sample output might assist you to understand these tasks.
