Implementing the InfoScreen class

This is a simple utility screen to display exceptions and alerts.

To create the class:

1. Assign the class to the package satsa and import the required classes.

   package satsa;
   
   import javax.microedition.lcdui.Alert;
   import javax.microedition.lcdui.AlertType;
   import javax.microedition.lcdui.Display;

2. Create the class by extending Alert.

   class InfoScreen
     extends Alert
   {
     InfoScreen()
     {
       super("InfoScreen");
     }
   
     void showError(String message, Display display)
     {
       setTitle("Error");
       setType(AlertType.ERROR);
       setTimeout(5000);
       setString(message);
       display.setCurrent(this);
     }
