Design a class "Student" that has private id, name, totalPoints (default = 0), gpa (default = 0), and array of grades (size = 3). The id should be generated automatically and incrementally for each new student and cannot be changed. The name should be initialized in the constructor and has a setter and getter. The class also has an addGrade that sets a grade for the student, a method calculatePoints that calculates the total points based on the student's grades, and a method calculateGPA that calculates the GPA of the student. Draw the UML diagram for the class. Write a test program that creates a student with the name "John Doe", set 3 grades for the student ('A','B', 'B'), calculate and print both the points and gpa. GPA is equal to (total points / 9). Points are calculated based on the following table: Grade A B C D F Point 12 11 10 9 0
