java.lang.Object | +--javax.microedition.lcdui.AlertType
The AlertType provides an indication of the nature of alerts.
Alerts are used by an application to present various kinds of
information to the user.
An AlertType may be used to directly signal the user without changing
the current Displayable.
The playSound method can be used to spontaneously
generate a sound to alert the user. For example, a game using a
Canvas can use playSound to indicate success or progress.
The predefined types are INFO, WARNING,
ERROR, ALARM, and CONFIRMATION.
