III. Programming Exercises Write source code for the following:

    Modify the Student class on page 306 in Chapter 6 as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore() that accepts two parameters: the test number (1 through 3) and the test score. Also provide a method called getTestScore() that accepts the test number and returns the appropriate score. Provide a method called average() that computes and returns the average score for this student. Modify the toString() method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods.
