JOptionPane Question

[Mike Sullivan]

If the application is started with incorrect number of command
line arguments, I need to display a Error message box on the center
of the screen. Once user presses ok on the message box, the
app needs to exit.
I am not really sure on how to handle this. Can some one help?

Hi Mike,
use:

if (errorcondition)
{
   JOptionPane.showMessageDialog(null, "message", "title", JOptionPane.ERROR_MESSAGE);
   System.exit(1); 
}
