Separating user-entered int into digits

Question

For example, if the user enters "123", separate it to 1, 2, 3. I've tried converting the int to a String and using charAt, and I've tried dividing: %10 and /10.
Here is my current charAt attempt:
public static void main(String[] args) {
          Scanner keyboard = new Scanner(System.in);
          System.out.print("What is the number? " );
          int num = keyboard.nextInt();
          String numString = String.valueOf(num);
        int numLength = numString.length();
      while (numLength >= 1) {
        int dig = (numString.charAt(numLength)) - 48;
          System.out.println(dig);
        int newNumLength = numLength --;
        dig = (numString.charAt(newNumLength)) - 48 ;
        System.out.println(dig);}
     }I was using - 48 because at first it was working for getting the first digit in the int.

Answer 1

If your String is "123", then your first character is '1', and you just want to print out the '1'. There's no need for the -48 part.
Try this:
int i1 = 48;
int i2 = '0';
System.out.println(i1);
System.out.println(i2);
char c1 = 48;
char c2 = '0';
System.out.println(c1);
System.out.println(c2);Edited by: jverd on Apr 11, 2011 5:18 PM
