MessageBox example

[Java Tip]

The example presented below shows different ways you can use JOptionPane.

Code:

public class MessageBox {

    /* 
    These are a list of STATIC MODAL dialogs

    int return codes of button pressed:

        -1 - WINDOW CLOSED - the X PRESSED
         0 - YES and OK
         1 - NO
         2 - CANCEL

    (thanks to flipside for the idea)
     */

    public static int yesno(String theMessage){
        int result = JOptionPane.showConfirmDialog((Component)
                null, theMessage, "alert", JOptionPane.YES_NO_OPTION);
        return result;
    }

    public static int yesnocancel(String theMessage){
        int result = JOptionPane.showConfirmDialog((Component)
                null, theMessage, "alert", JOptionPane.YES_NO_CANCEL_OPTION);
        return result;
    }

    public static int okcancel(String theMessage){
        int result = JOptionPane.showConfirmDialog((Component)
                null, theMessage, "alert", JOptionPane.OK_CANCEL_OPTION);
        return result;
    }

    public static int ok(String theMessage){
        int result = JOptionPane.showConfirmDialog((Component)
                null, theMessage, "alert", JOptionPane.DEFAULT_OPTION);
        return result;
    }

    public static void main(String args[]){
        int i = MessageBox.yesno("Are your sure ?");
        System.out.println("ret : " + i );
        i = MessageBox.yesnocancel("Are your sure ?");
        System.out.println("ret : " + i );
        i = MessageBox.okcancel("Are your sure ?");
        System.out.println("ret : " + i );
        i = MessageBox.ok("Done.");
        System.out.println("ret : " + i );
    }
}
