Question
Q1. Suppose we have a University System. The university has three departments CS, IT and CNET.
Each department has students, the students can be regular students or irregular
students.Following are the classs and attributes in the university system:
Class University, Fields : University_Name, University Type, Location.
class IT Dept, Fields: Dept code.
class CS Dept, Fields : any 2 fields
class CNET Dept, Fields : any 2 fields
class Student, Fields : studentName, studentID.
Class ReglarStudent, Fields : any fields of your choice
Class IrregularStudent, Fields: any fields of your choice
class StaffMembers, Fields: staffID.
a) Define all the given classes and Draw an inheritance relationship between the classes in a
best possible way. The University class should have a list of staff members, use
ArrayList<StaffMembers>. All the methods in the university class should be declared as
protected.
b) Declare a method display) in the university class and override the display() method in all
subclasses.
c) In class CS Dept, show how the call to a base class contrcutor is made.
