    Lightbulb how to repeat a task again after it has been done

    hey guys.

    my code is simply made for rolling a 20 faced cube:


    import java.util.Scanner;
    import java.util.Random;
    public class in {
    public static void main (String args[]){
    Scanner d = new Scanner (System.in);
    Random a = new Random();
    int b;
    b = 1+a.nextInt(20);
    System.out.println("press 0 to roll a 20 cube");
    int c;
    c = d.nextInt();
    if (c == 0){
    System.out.println(b);
    }
    }
    }

    I want the applet to again ask to press zero so they can roll the die again and get another random number, and not for the applet to end. help will be greatly appreciated

    Use a loop to repeat a section of code. For this, the while loop would work.
    Put the while(...) { at the beginning
    and a } at the end of the statement to be repeated.
    Use Search to find plenty of code samples.
