Java - adding value in a while loop

Question

this one just is hurting my brain. http://programmingbydoing.com/a/adding-values-in-a-loop.html

Write a program that gets several integers from the user.

Answer 1

import java.util.Scanner;

public class AddingInLoop {
    public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);

        int number, total = 0;

        System.out.print("Enter a number\n> ");
        number = keyboard.nextInt();
        total += number;

        while (number != 0) {
            System.out.print("Enter another number\n> ");
            number = keyboard.nextInt();
            total += number;
        }
        System.out.println("The total is " + total + ".");
    }
}

You first prompt the user to enter a number. Then you store that number into total (total += number OR total = total + number). Then, if the number entered wasn't 0, the while loop executes. Every time the user enters a nonzero number, that number is stored in total ( the value in total is getting bigger) and the while loops asks for another number. If and when a user enters 0, the while loop breaks and the program displays the value inside total. :D I myself am a beginner and had a bit of an issue with the logic before figuring it out. Happy coding!
