OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Question

Given a base class with the following UML class diagram. Create a Person base class for the
following. You have to create a NetBeans project for this question.
Person
- name: String
+ setName(String newname): void
+ getName( ): String
+ writeOutput ( ): void
+ equals (Person otherPerson): boolean
You have to use the base class Person you have created to derive a class named as Student
that can be used for the objects for students in a university. The employee record will inherit
a student's name from the class person. A student record will contain the GPA score
represented as a single value of type double, a starting date that gives the year that student
started the course as a single value of type int, and a student identification number that is a
value of type long.
You have to provide your solution with the following guidelines.
• Provide the Person Base Class (2 marks)
• You have to provide the derived Student class from Person class and take care of the
following.
• Provide appropriate private instance variables for the information required in the
derived class. (2 marks)
• Explain and demonstrate the importance of using private instance variables. (2
marks)
• Provide a default constructor and all other necessary constructors required for the
derived class. (2 marks)
• Provide all necessary mutator and accessor methods in the derived class. (2 marks)
• Provide a writeOutput and equals methods in the class Student. (2 marks)
Using the class Student that you have created to explain the differences between
overloading and overriding methods using the methods in class Person and class
Student. (2 marks)
• Using the class Person and class Student, explain what is polymorphism and provide
an example of how you can use the two classes to illustrate the concepts of
polymorphism. Note: if you just provide definition of polymorphism without using
code and example for the classes to explain, you will receive 0 mark for this part. (4
marks)
Provide a client class such that you can demonstrate the use of the derived Student
class and for testing purposes. (2 marks)
NOTE: If your project file cannot be run, you will only receive 50% of the marks of this
question. Test it before submission.
Remember to submit your NetBeans Project file.
