Question

I have a integer value coming from command line. Its like 12345 or 2343455435 without any delimit characters. How can I get individual pieces of that integer, say like for 12345 I want something like 1, 2, 3, 4 and 5.

Answer 1

Just iterate over all chiffres of the Integer and add a comma if necessary. Something like that:

public static void main(String[] args) {
        int a = 123456;

        String s = Integer.toString(a);
        for (int i = 0; i < s.length() - 1; i++) {
            System.out.print(s.charAt(i) + ",");
        }
        System.out.println(s.charAt(s.length() - 1));
    }
