I do the class but there are some codes I need to help me please :
-Write a number of member functions that do the following:
•Calculate the student GPA
•Search for the highest mark taken in a particular course
•Print the ID, first name, and last name of all the students who have already taken a particular course
•Print the course code, course title, course mark, course grade of all courses taken by a particular student
-Write a main program that does the following:
•Define an array of objects of each one of the above three classes
•Assign data to the objects that you defined. This data should be stored and read from 3 different files
•Read a student ID
•Print a list of all courses taken by that student
•Calculate the GPA of that student
•Read a course code
•Print the ID, first name, and last name of all the students who have taken that course
•Search for the highest mark taken in that course
•Print the ID, first name, and last name of the student who scored that highest mark in that course

-StudentType

        super();

        this.studentId = studentId;

        this.firstName = firstName;

        this.lastName = lastName;

        this.major = major;

    }

    public int getStudentId() {

        return studentId;

    }

    public void setStudentId(int studentId) {

        this.studentId = studentId;

nourimane commented: Hi, +0

And what are you willing to pay to have someone do your homework for you?

What have you tried so far ?

Hi,

All you have done is the data part, no more, so you have data that will be put in a List (ArrayList) so it's like you have multiple students, courses and marks. Then every point on your list must be a method (a function).

It's a start, we'll wait for your progression.
