Q4:

Draw an Inheritance hierarchy for students at a university similar to the hierarchy as shown in the Figure below.

Figure: Inheritance hierarchy for university CommunityMember

Use Student as the superclass of the hierarchy, then extend Student with classes UndergraduateStudent and GraduateStudent. Continue to extend the hierarchy as deep (i.e., as many levels) as possible. For example, Freshman, Sophomore, Junior and Senior might extend UndergraduateStudent. DoctoralStudent and MastersStudent might be subclasses of GraduateStudent. After drawing the hierarchy, discuss the relationships that exist between the classes.
