Show a message dialog with JOptionPane


This code example shows how to easily display a message dialog using the Swing class JOptionPane.



public class myFrame extends JFrame {

   //....

   public void displayMessage() {

      JOptionPane.showMessageDialog(this,
                                    "The message",
                                    "The Title",
                                    JOptionPane.INFORMATION_MESSAGE);
   }
}


If you want an icon on the dialog, provide an instance of the
Icon class as a fifth parameter to showMessageDialog().
