I am trying to format add a zero to any value less than 10, so 09. So at the end of the loop, the "total" value will format to numbers less than 10 with a zero.

Here is my code but it still isn't working :

int total = 0;

String holder = val + "-" + s + "-" + frame + "-";
    for (int i = 0; i < holder.length(); i++)
    {
        int mod = holder.charAt(i);
        total += mod;
        total = total%100; //get remainder
    }

string totalchk = String.format("%02d", total);

Assign the result of `String.format` to a variable. – Elliott Frisch Dec 10 '15 at 19:59
And you probably want to do your formatting after all is said and done, after the `for` loop. If you assign the result of `String.format` to a variable in the second line, your result will be `00` every time. – dcsohl Dec 10 '15 at 20:03
@ElliottFrisch I have updated the code, but I get "cannot find symbol - class var" – newborn Dec 10 '15 at 20:10
`string` != `String`. – Elliott Frisch Dec 10 '15 at 20:28
