Question

In Java, write an application that inputs one number consisting of five digits from the user, separates the number into its individual digits and prints the digits separated from one another by three spaces each. For example, if the user types in the number 42339, the program should print 4 2 3 3 9

import javax.swing.*;

public class Main {

    public static void main(String[] args) {

        /* taking user input using GUI input dialog */
        String num = JOptionPane.showInputDialog("Enter 5 digit number: ");

        /* storing the num string into a string array num_str */
        String num_str[] = num.split("");

        /* taking an empty string for result storing */
        String result = "";
        for (int i = 0; i < num.length(); i++) {

            /* inserting spaces between digits */
            result = result + num_str[i] + "   ";

        }

        /* creating a new frame for output message dialog */
        JFrame f = new JFrame();

        /* displaying the output using GUI dialog */
        JOptionPane.showMessageDialog(f, result);

    }
}
