keep track of a student's information from the class Person , and one member of the
class Student is of type Course . We can add more members as needed.
The basic operations to be performed on an object of type Student are as follows:
1. Set the student information.
2. Print the student information.
3. Calculate the number of credit hours taken.
4. Calculate the GPA.
5. Calculate the billing amount.
6. Because the grade report will print the courses in ascending order,
sort the courses according to the course number.
Next, we define the members of the class Student .
Instance Variables:

private int sId; //variable to store the
//student ID
