Im getting this stupid error...

[NycCraze88]

Im wondering what I need to do to fix this problem....here 's the piece of code:

private static int checkDigits(Str ing choice2) {
char[] chars = String.valueOf( choice2).toChar Array();
int check = 0;
for (int j = 0; j < chars.length; j++)
check += Integer.parseIn t(String.valueO f((int)pow(10, 14-j)*chars[j]));
int digit = Integer.parseIn t(String.valueO f(chars[14]));
return digit;
}
}

Basically, i need to implement the Airline Ticket check digit scheme....and we need to save it in a char array but i need to use the power function and its giving me this error:

"The method pow(int, int) is undefined for the type AirTicketNums"

How do I solve this? I tried casting and nothing...

anybody? This error is really pissing me off

What is the specification for that algorithm? pow or no pow it makes no sense.

[NycCraze88]

its supposed to use the formula that verifies if the check digit is correct on the inputted number......the formula is:


14
Sigma 10^(14-i) X Ai = A15 mod 7
i=1

i can post the whole code if you want..

I would avoid doubles -- I'd be concerned about rounding errors. So instead of using pow, I would just do the math and work in longs.

I solved the problem. thanks anyway, you guys can delete this thread.
