    Default Seperate numbers

    So i've got a little proble with my code. The idea is to take a number for example 1234567890 and seperate its digits to : 1,2,3,4,5,6,7,8,9,0 or 0,9,8,7,6,5,4,3,2,1...For that a thought an algorithm but it doesnt work. Could u please check it!?!?!
     
    package javaapplication16;
     
    public class JavaApplication16 {
      public static void main(String[] args) {
        int x =1234567890;
        int y;
        for(int i = 1; i<10; i++){
          y = x % 10^i/10^(i-1);
          System.out.println(y);
      }
     }
    }

    Try separating the digits out one step at a time using the % and the / operators
    instead of trying to do it all in one expression.
    If you don't understand my answer, don't ignore it, ask a question.

    What does the code print out now?
    I dont understand why it doesnt work that way
    Try debugging the code by breaking that big expression up into single steps and print out the results at each step so you can see what the code is doing.
    If you don't understand my answer, don't ignore it, ask a question.

    As a side note:
    int x =1234567890;
    for(int i = 1; i<10; i++)
    I can see that x is 10 digits, but the algorithm i see in my head would work for x with any number of digits
