How to get the separate digits of an int number?

Question

I have numbers like 1100, 1002, 1022 etc. I would like to have the individual digits, for example for the first number 1100 I want to have 1, 1, 0, 0.

How can I get

Answer 1

Here is my answer, I did it for myself and I hope it's simple enough for those who don't want to use the String approach or need a more math-y solution:

public static void reverseNumber2(int number) {

    int residual=0;
    residual=number%10;
    System.out.println(residual);

    while (residual!=number)  {
          number=(number-residual)/10;
          residual=number%10;
          System.out.println(residual);
    }
}

So I just get the units, print them out, substract them from the number, then divide that number by 10 - which is always without any floating stuff, since units are gone, repeat.
