import java.util.Random;
import java.util.Scanner;

public class MathQuiz {
    public static void main(String[] args) {
        System.out.println("Welcome to multiplication quiz!\n\n");
        // random for generating random number
        Random rand = new Random();
        Scanner scanner = new Scanner(System.in);
        int num1, num2;
        while (true) {
            // generating random number between 0 and 100 
            num1 = rand.nextInt(99) + 1;
            num2 = rand.nextInt(99) + 2;
            System.out.println(String.format("What is %d × %d?", num1, num2));
            // scanning the user answer
            int userAnswer = scanner.nextInt();
            // computing the correct answer
            int correctAnswer = num1 * num2;
            // comparing the answer and printing result accordingly
            if (userAnswer == correctAnswer) {
                System.out.println("Correct Answer");
            }
            else System.out.println("Sorry! Incorrect Answer, Correct Answer is : "+correctAnswer);
            // asking if want to play again
            System.out.print("Do you continue want to play[y/n]? ");
            String choice = scanner.next().toLowerCase().trim();
            if(choice.charAt(0)=='n'){
                System.out.println("Thanks for Playing!!!");
                break;
            }
