Create a dialog box

Use alert dialog boxes to notify users of a critical action such as turning off the BlackBerry® device or an error such as typing information that is not valid. An exclamation point (!) indicator appears in an alert dialog box. To close an alert dialog box, users can click OK or press the Escape key. For more information on other types of dialog boxes, see the API reference for BlackBerry® Java® Development Environment.
