public class CheckMenuItemExample extends Application {
@Override
public void start(Stage stage) {
//Creating a menu
Menu fileMenu = new Menu("File");
//Creating menu Items
Menu view = new Menu("View");

MenuItem exit = new MenuItem("Exit");
//Creating menu items for the sub item edit
CheckMenuItem sub1 = new CheckMenuItem("Status Bar");
CheckMenuItem sub2 = new CheckMenuItem("Address Bar");
