For this assignment you will write classes to grade a multiple-choice exam for up to 20 students. For each student the program will read in an identification number and that student's answers on a multiple-choice test. The exam is "graded" by comparing a students' answers to the answer key. The percent right is computed and stored along with the student id number. After all exams have been graded, the program produces the results in two ways:
Below is a sample run. Your program should produce similar, but not necessarily identical, output:

Copy the code for class Student which defines a Student object with two fields: id number and test score from~wenk/cs132/lab6. It also contains the methods for accessing and changing these values.
You are asked to write a class GradeExam which creates an array of Student objects and implements methods to:
You will also need to write class Grade which creates an object of type GradeExam and calls its methods to process the students' exams. It should call at least one static method.
Turn in hardcopies of GradeExam.java and Grade.java as well as a script of you running the program.
