How to exit after showing alertbox?

[gracy]

I want to exit the program after showing the alert.
So I display the alert and call notifyDestroyed()
display.setCurrent(alert)
alert.setTimeout(Alert.FOREVER);
notifyDestroyed();

But the program exit without showing the alert.
So I write the following way.
Is there any better way?

alert=new Alert("","***********************",null,AlertType.ALARM);
			display.setCurrent(alert);
			alert.setTimeout(Alert.FOREVER);
			cmdExit=new Command("Exit",Command.EXIT,0);
			alert.addCommand(cmdExit);
			alert.setCommandListener(this);
			
		}
		
		else
			display.setCurrent(mainform);
			
		

	}

	public void commandAction(Command c, Displayable d) {
		notifyDestroyed();
		
	}

One more solution, add the command on the Alert and show the same when the Alert is displayable. Now you can handle the command handling inside the commandAction(), like if command is exitCommand then call the method which exits the app.
