The Dialog class provides a special type of display window that is used for pop-up messages and acquiring input from the user. Unlike most other components, dialogs are hidden by default; you must call show() to display them. Dialogs are always associated with a parent Frame. A Dialog may be either modal or non-modal; a modal dialog attracts all input typed by the user. The default layout for a Dialog is BorderLayout.
