TestScores Class

Design a TestScores class that has fields to hold three test scores. (If you have already written the TestScores class for Programming Challenge 8 of Chapter 3, you can modify it.) The class constructor should accept three test scores as arguments and assign these arguments to the test score fields. The class should also have accessor methods for the test score fields, a method that returns the average of the test scores, and a method that returns the letter grade that is assigned for the test score average. Use the grading scheme in the following table:
