5. Add Image to the Menu

5.1. Open ViewStudentApp class and add menu items inside the constructor.
5.2 Add add, edit and delete student options to the menu and set commands to execute:

      MyScreen _mainScreen = new MyScreen(this);       
       
        MenuItem addItem = new MenuItem(new StringProvider("Add Student"), 200, 2);
        adds.setCommand(new Command(new AddCommandHandler()));
        _mainScreen.addMenuItem(addItem);
       
        MenuItem editItem = new MenuItem(new StringProvider("Edit Student"), 300, 3);
        edit.setCommand(new Command(new EditCommandHandler()));
        _mainScreen.addMenuItem(editItem);
       
        MenuItem delete = new MenuItem(new StringProvider("Delete Student"), 400, 4);
        delete.setCommand(new Command(new DeleteCommandHandler()));

        }
    }
    class EditCommandHandler extends CommandHandler
    {
        public void execute(ReadOnlyCommandMetadata metadata, Object context){
            Dialog.alert("Edit was selected");
        }
    }
    class DeleteCommandHandler extends CommandHandler
    {
        public void execute(ReadOnlyCommandMetadata metadata, Object context){
