Question

You are responsible for adding the appropriate testing code to your main.

a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method.

b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program.

c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array.  Show how the declaration of the data field students would look in this alternate design.
