Java/ApComputerSci., User input programs Options

[SkaironFrenzy]

{OK i'm pretty much new to Java and the computer language thing, but I do understand the fundamentals.}

Due:Wednesday, 21,2005

Problem:

Write an application program that inputs one number consisting of four digits from the user; separates the number into its individual digits and prints the separated digits from one another. For example, if the user types in the number 4239, the program should print 4 2 3 9.(hint:Use Mod(%) and Division(/).

Ok this is what I got so far:

import javax.swing.JOptionPane;

public class Separate
{
public static void main(String[] args)
{
String number;
int numberOne;
double mod;
double division;

number=JOptionPane.showInputDialog("Enter 4 numbers");
numberOne= Integer.parseInt(number);


System.exit(0);
}
}

(I tried putting a code box but it screwed up the code.)
Its just the foundation. I cant figure out the rest to separate the numbers. Thanks you all for your help.

Okay, well, I didn't feel like building an interface to test this, but I built it as a command-line applet. Here's what I did:

CODE

public class SplitNum
{
   public static void main(String[] args)
   {
       TextReader keyboard = new TextReader(); //this is just a class i built for easily getting keyboard input

       System.out.print("Enter number: ");
       int num = keyboard.readInt();

       String num_string = new String();
       num_string = num_string.valueOf(num); //read number as a string

       int i = 0;
       for (i = 0; i < num_string.length(); i++) {
           System.out.print(num_string.charAt(i) + " "); //output specific character of string
       }
       System.out.println();
   }
}

Here's what the output looks like:

CODE

athena{~/csci203/practice}% java SplitNum
Enter number: 4329
4 3 2 9

It shouldn't be too hard to convert it into a Swing applet.

It doesn't use division or mod, but hey, it works fine.
