Prompt on close closing on no

Question

I am not sure what I am doing wrong here but if the user clicks no the program closes anyway.
//Sets a propmt for closing the window
         setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
         addWindowListener( new WindowAdapter()
           @Override
          public void windowClosing(WindowEvent e)
            int selection = JOptionPane.showConfirmDialog(null,
                             "Do you want to close the window?", "Program Title",
                             JOptionPane.YES_NO_OPTION,
                             JOptionPane.WARNING_MESSAGE);
                     if( selection == JOptionPane.YES_OPTION )
                         // If the user answered "Yes", we close the frame
                         dispose();
                         // and call System.exit(0) if the whole application
                            // should
                         // terminate:
                         System.exit(0);
                     // If the user pressed "No" we don't have to
                     // do anything.
                        else
                            if( selection == JOptionPane.NO_OPTION)
        });

::sigh:: No what you have posted has not worked or helped so far...here is the code in its entirety and I can not edit the Netbean's "setDefaultCloseOperation(javax.swing.WindowConstants.DISPOSE_ON_CLOSE);".
