    Default Why is the answer not coming out

    public class Lab8_Ex1
    {
    public static void main(String [] args)
    {
    int sum = 0;
    int n = 10;
    compute_sum(n);
    System.out.println(“The sum is “ + sum);
    System.exit(0);
    }
    public static void compute_sum(int x)
    {
    int sum = 0;
    int num = 1;
    while (num <=x)
    {
    sum += num;
    num++;
    }
    }
    }

    It's supposed to sum up the no. 1-10

    Default

    you need to return values from a method call for them to be used. You are printing a number that is initialized to zero and is never modified.

    Ok, so I'm guessing I would have to put a return; in the program but I'm still not really understanding should I change oner of the initialized zeros, and I put a return in and still got the same thing, could it be in the wrong place

    Default Return the value...

    What emceenugget is telling you to do is return the result of the sum you need from the compute_sum method... something like
    Java Code:
    return (sum);
    In the main method you have to pick up the sum with
    Java Code:
    sum = compute_sum(n);
