I am stuck with this java program. I need to modify it so that it asks the user if they want to play the quiz over and over until the user enters "n" or "N". When they answer N or n, the program will stop.

Here is a sample run:

Do you want to play the Addition Quiz (answer Y or N)? Y

What is 1 + 3? 4

Your answer is correct!

Do you want to play the Addition Quiz (answer Y or N)? Y

What is 1 + 2? 6

Your answer is wrong!

1 + 2 should be 3

Do you want to play the Addition Quiz (answer Y or N)? N

Thanks for playing the Addition Quiz Game! Bye!

// 1. Generate two random single-digit integers

Scanner input = new Scanner(System.in);
int answer = input.nextInt();

String replyString;
if (number1 + number2 == answer)
replyString = "You are correct!";
else
replyString = "Your answer is wrong.n" + number1 + " + "

System.out.println(replyString);
