Create a java application that grades a multiple choice quiz.

The application will do the following:

Prompt the user to enter the number of questions for the quiz, then prompt the user to enter the answer key for each question. Use an array.

Prompt:

Create an array of Students that will contain the students name and grade on the quiz.

From a file, read each students name and quiz answers.

By comparing the entered answers to the answer key, the program can determine if the answer is correct or incorrect. Count the correct answers and store the final score for each student.

Display a report of students' grades, the highest grade, the lowest grade, and the average score for the class.

This is the error message:
