How do I split display Numbers?

Question

I have been given the task of finding the sum, quotient and remainder of two input integers. Not that much of a problem.
But the problem now is, I am supposed to display the digits entered with the numbers being separated by two spaces.
In example, if the number is 5678
the display should be
5 6 7 8
How?
Thank you..

import javax.swing.*;
class Question1 {
     public static void main (String args[]){
          Question1 theObject = new Question1();
          String strA = "";
          String strB = "";
          int a = 0;
          int b = 0;
          int qoutient = 0;
          int remainder = 0;
          for ( ; ;)
          strA = JOptionPane.showInputDialog("Please enter 1st integer : ");
          a = Integer.parseInt(strA);
          if (a==0)
          break;
          strB = JOptionPane.showInputDialog("Please enter 2nd Integer : ");
          b = Integer.parseInt(strB);
          if (b==0)
          break;
          qoutient = a / b;
          remainder = a % b;
          int displayA = displayDigits(a);
          int displayQoutient = displayDigits(qoutient);
          int displayB = displayDigits(b);
          int displayRemainder = displayDigits(remainder);
          JOptionPane.showMessageDialog(null, "The Digit a is "+ displayA + "\nThe Digit B is " + displayB
               +"\nThe quotient is " + displayQoutient + "\nThe Remainder is " + displayRemainder,
               "Digits Displayed", JOptionPane.INFORMATION_MESSAGE);
     }//end main method
     public static int displayDigits(int number){
          int placeValue = number % 10;
        number = number / 10;
        int reverseNumber = 0;
        reverseNumber = reverseNumber * 10 + placeValue;
        return reverseNumber;
}That was how far I Got, but I am reversing numbers instead.
How do I use the charAt method which you recommended?
