MIDLET

In MIDP, when you develop a program actually you develop a midlet.

Midlet : javax.microedition.midlet.MIDLET class, which contains main application management functions, is a interface between application management software(AMS) and MIDP application.

Every MIDP application must extend MIDLET class

As you see below our HelloPhone midlet extends from Midlet class and implements CommandListener.

startApp() : When program starts it call this method but it maybe recalled again and again during program.

pauseApp() : Simply pauses midlet.When user wants to continue executing program midlet invokes startApp()

destroyApp(boolean unconditional) : Ends program and release sources.If boolean unconditional set to true middlet have to release sources immediately.But if it is set to false middlet can throw "MIDletStateChangeException" to continue executing.
