Jay be trollin' Any ways, your classes are 99% useless, the 1% use is well, to assist me in crying when people don't know what they're doing.

Hi Jacob! :)

import javax.swing.JOptionPane;

public class DoAgain {
    public static boolean ask() {
        String again;
        do {
            again = JOptionPane.showInputDialog("Again? y or n? ");
            System.out.println("Again? y or n? " + again);
        } while (again.equals("y") && !again.equals("n"));
        return again.equals("y");
    }
}

public class IO {

    public static int getInt(String message) {
        int num = 0;
        try {
            num = Integer.parseInt(JOptionPane.showInputDialog(message).trim());
            System.out.println(message + ": " + num);
        } catch (NumberFormatException e) { // test for bad input
            System.err.println(e.toString()); // error message

            return '\0';// null char
        } else {
            System.out.println(message + ": " + s.charAt(0));
            return s.charAt(0); // first char
        }
    }

    public static void println(String message) {
        System.out.println(message);
        JOptionPane.showMessageDialog(null, message);
    }

}

Generic knows way more Java than you do, just saying.

Only if you public static main void(String[] args) is in the same file, if you're calling functions from a different java file you have to create the object

You don't need to create a new object if all your doing is accessing static methods from the class.
