Objectives: In this lab, the following topic will be covered: 1. Abstract Classes Task Design an abstract class Student. A student has the following data fields: Id and GPA. The student class has an abstract method getStatus that returns the status as a string. Design two subclasses Undergraduate and Graduate. The status of the graduate student is good if his GPA is 3.0 or above otherwise it is probation. The undergraduate's status is honor if his GPA is 3.0 or above, good if his GPA is 2.0 or above, probation otherwise. Write a test program that declares an array of type Student. Make some elements Undergraduate objects and some elements Graduate objects with random values. For every student, print his Id, GPA, and status. Notes: Save every class in a separate file. Data fields should be private. Constructors and methods should be public. . Sample output: the word Undergraduate or Graduate will be displayed using instanceof operator Undergraduate: id: 123 gpa: 3.5 status: Honor Graduate: id: 734 gpa: 3.7 status: Good Graduate: id: 778 gpa: 2.4 status: Probation Undergraduate: id: gpa: 2.5 status: Good Undergraduate: id: 524 gpa: 1.5 status: Probation
