Overriding and Overloading

Based on the characteristics of overloading and overriding in the lecture, one of them was that (constructor is able to be overloaded), the other was that (overriding has advantage in providing specific implementation of a method that is already provided by its superclass.)

1- Create two classes; The first called: StudentData, and the second called: CSStudents )

2- The classes are created to provide the structure for three objects of students st1, st2, and st2.

3- Class StudentData defines :

Four of private attributes called (studentID, studentName, courseMark, numberOfHoursInCourse). These attributes have no initialization.

Two of public attributes called (courseGradeNumberOfFive, courseGradeLetterOfFive). These attributes have no initialization.

One Behavior called ( calculateGPA ): To calculate the point of the GPA of 5 for a provided course.

3- Class CSStudents defines :

Three private attributes called (courseName, numberOfHoursInCourse, courseMark).

Two public attributes called (courseGradeLetterOfFour, courseGradeNumberOfFour ).

One Behavior called ( calculateGPA) To calculate the point of the GPA of 4 for a provided course, also it implements the function to calculate the Grade for the point of 5 and the point of 4 as well.

4- Show the ability of the constructor for overloading by using two constructors:

One to initialize studentID, studentName.

One to initialize studentID, studentName, courseName, courseMark,   numberOfHoursInCourse

6- Show the advantage of the overriding in providing its specific implementation of calculateGPA method in class CSStudents , that is already provided by class StudentData.

7- Implement the three objects from the second class.

8- Display the structure for three objects from the main class to get as same as output below.

9- You may need more instance methods to complete your homework.

10- You may need more Overriding methods to complete your homework.

11- Provide your code and the implementation in Java code.
