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

Just to build on the subject, here's how to confirm that the number is a palindromic integer in Java:

public static boolean isPalindrome(int input) {
List intArr = new ArrayList();
int procInt = input;

int i = 0;
while(procInt > 0) {
    intArr.add(procInt%10);
    procInt = procInt/10;
    i++;
}

int y = 0;
int tmp = 0;
int count = 0;
for(int j:intArr) {
    if(j == 0 && count == 0) {
    break;
    }

    tmp = j + (tmp*10);
    count++;
}

if(input != tmp)
    return false;

return true;
}

I'm sure I can simplify this algo further. Yet, this is where I am. And it has worked under all of my test cases.

I hope this helps someone.
