    Default 0-10Factorial table

    How can I make a factorial table for the numbers 0-10...I want it printed so 0 1, 1 1, 2, 2, 3 6 etc, but I do not know how.

    This is only for the numbers 1-30, but I don't know how to calculate its factorial and match it up with the given integer.
    public static void factorial() {
    int sum, number = 10;
    for (int i = 1; i <= number; i++)
    {
    System.out.print(i + "\t");
    sum = 1;

    What are you stuck on? Figuring out the algorithm for factorials or how to put it to code?

    Are you looking for a recursive solution our something straight forward?

    something straightforward, i'm pretty sure the recursive way needs the method to be an integer but that requires return statements.

    Ok, so you're trying to write an iterative (non-recursive) factorial program. If you have the iterative factorial algorithm, which part is causing you problems? Or do you not have an iterative factorial algorithm?

    A factorial is simply the number multiplied by all numbers previous to it.

    8! = 8*7*6*5*4*3*2*1 or 1*2*3*4*5*6*7*8

    Looks like a simple for loop to me. Google "iterative factorial algorithm" if you're still having issues with the algorithm after seeing this explanation.
