Given the following class definition write the code for the method getGPA() and the javaDocs that explain what the method does and how GPA is calculated:

public class Student { private int studentID; private String name; private Schedule schedule; private int gradePoints; private int numberOfCredits; public student(String name, int ID) { this.name = name ; studentID = ID; } public double getGPA() { // <<< your code goes here >>> } private double calculateGPA() { // (double) in the next line of code 'casts' (forces) gradePoints to be a type double in this line // of code so that the division will return a real number instead of an int double gradePointAverage = (double)gradePoints/numberOfCredits; return gradePointAverage; } // more code }
