array coursesEnrolled by course number. The class Student is derived from
the class Person , and the variables to store the first and last name are private
members of that class. Therefore, we call the method setName of the class Person ,
and we pass the appropriate variables to set the first and last names. The definition of
the method setInfo is as follows:

public void setInfo(String fName, String lName, int ID,
int nOfCourses, boolean isTPaid,
Course[] courses, char [] cGrades)

{

setName(fName, lName); //set the name

sId = ID; //set the student ID

isTuitionPaid = isTPaid; //set isTuitionPaid

numberOfCourses = nOfCourses ; //set the number of courses

for ( int i = 0; i < numberOfCourses; i++) //set the array
{

coursesEnrolled[i].copyCourseInfo(courses[i]);
courseGrades[i] = cGrades[i];

}

sortCourses(); //sort the array coursesEnrolled

}

The definitions of the methods setStudentId , setIsTuitionPaid ,
setNumberOfCourses , and setCoursesEnrolled are similar to the definition of
the method setInfo , and are given next.
