How the heck is this gonna work.....

String fname = "Cameron";
    String lname = "Doherty";

    Calendar c1 = new GregorianCalendar();
    Date d1     = new Date("1/20/02");
    c1.setTime(d1);

    int days = c1.get(Calendar.DAY_OF_YEAR);
    String fdays;
    if (days <= 9) fdays = "00" + days;
    else if (days <= 99) fdays = "0" + days;
    else fdays = "" + days;

    while(??????)
    {
    }

Ok the problem goes like this. I am making a block of code that will take the entered first name, last name, and date and convert it into a tracking code. So for instance. The above code would be printed out into a tracking code of CD0208. The code has to be 6 characters in length and the last number HAS to have the day of the year number add up to something that ends in 0. For instance, 1/20/02 is the 20th day of the year, so that will be show in the code, as shown before, as 020. 0+2+0 = 2. So to make those numbers have a sum that is divisble by 10, we have to add 8. Hence the final code is 0208. Making sense? hehe. Its a strange requirement from my teacher but whatever. So obviously it will be a loop but Im having trouble figuring out a suitable tester for the loop(to test after each run through of the loop)...hence the ????? in the posted code. Also is this more suitable in a for loop?

So just wanted to get some ideas from some more experienced users Thanks in advance.

Forgot...I was converting it to a string so I could add the necessary 0's and also so that when I wanted to add up all the individual digits....I could just use:

int a = Integer.parseInt(fdays.substring(0,1));

and so on.

figured a workaround...no loop needed

if ( (a+b+c) >=11) digit = 20 - (a+b+c);
else digit = 10 - (a+b+c);
