    Default Multiplication program

    Hi guys! I have created a program that is designed to ask students multiple equation questions. The program will only be designed to ask single digit numbers. I have managed to create the questions and a random number generator, but i want this program to constantly loop, any ideas on how to implement a loop?

    Heres my code:
    import java.util.Scanner;
     
    public class SubtractionQuiz {
    public static void main (String[] args) {
    int number1 = (int) (Math.random() * 10);
    int number2 = (int) (Math.random() * 10);
     
     
     
    System.out.println("What is" + number1 + " * " + number2 + "?");
    Scanner input = new Scanner(System.in);
    int answer = input.nextInt();
     
     
    if (number1 * number2 == answer)
    System.out.println("You are correct!");
    else
    System.out.println("Wrong!");
     
     
     
    }
    }

    Thanks in advance!

    What kind of looping statements do you know about? Which one do you want to use?
    When do you want to exit the loop? On user request or after a number of tries?
    If you don't understand my answer, don't ignore it, ask a question.
