Question

This is the question -

Create an abstract Student class for Parker University. The class contains fields for student ID number, last name, and annual tuition. Include a constructor that requires parameters for the ID number and name. Include get and set methods for each field; the setTuition() method is abstract.

Create three Student subclasses named UndergraduateStudent, GraduateStudent, and StudentAtLarge, each with a unique setTuition() method. Tuition for an UndergraduateStudent is $4,000 per semester, tuition for a GraduateStudent is $6,000 per semester, and tuition for a StudentAtLarge is $2,000 per semester.

Code I was given -

public class GraduateStudent extends Student
{
    public static final double GRAD_TUITION = 6000;
    public GraduateStudent(String id, String name)
    {
        // write your code here 
    }
    public void setTuition()
    {
        tuition = GRAD_TUITION;
    }
}
 
public abstract class Student

            System.out.println("\nStudent # " +
                    students[i].getId() + " Name: " +
                    students[i].getLastName() + "  Tuition: " +
                    students[i].getTuition() + " per year");
    }
}
public class UndergraduateStudent extends Student
{
    public static final double UNDERGRAD_TUITION = 4000;
    public UndergraduateStudent(String id, String name)
