code :
<?php
$value = 35482;
echo $value%10;

I wish this help you I need to write a Java program that validates credit card numbers, and to do that I need to preform operations on each individual digit. How can I get these digits, without using strings or arrays?
code :
int number; (This would be your credit card number)

while (number > 0) {
    System.out.println( number % 10);
    number = number / 10;
}

around this issue newNumber2 % 10 returns the last digit of newNumber2. a % b is the remainder of a divided by b - so this is the remainder of newNumber2 divided by 10, which happens to be the last digit.
So you can use, for example:
code :
if((newNumber2 % 10) == 1)
