Provide a JUnit test class StudentTest with three methods, each of which tests a different method of the Student class in How To 7.1 (pages 330-332).

here is the student class

public class Student

Constructs a student with no scores and a maximum number of scores.

Adds a score for this student.

score

if there are no scores.
