CODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments)   1. Ask the user how many questions are in the quiz.   2. Use a for loop to load the array.  Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key".   3. Ask the user to enter the student's answers for the quiz to be graded.  There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered.  If the answer is correct, add 1 to a correct answer counter.  need this in a separate for loop from the loop used to load the array.   4. When the user has entered all of the answers to be graded, print the number correct…
