Exiting loop with numeric input from user

Vote count:

may I ask what are some proposed solutions to this issue? When the user enters -1, this will be included into the total, which is not what we want. I am trying to do this without the use of an if control structure.

    int numberToAdd = 0, total = 0;
    Scanner input = new Scanner(System.in);

    while (numberToAdd != -1) {
        System.out.println("Number to add? -1 to quit");
        numberToAdd = input.nextInt();
        total = total + numberToAdd;
    }
    System.out.println("Total: = " + total);

I am aware that I can instead use strings and use an exit code that is a string, whilst parsing String inputs as an integer, however I am trying to accomplish that with an integer (in this case, -1).

Thanks
