Я создал класс PizzaMenuView, содержащий большое количество кода, например, GUI.Я не могу заставить его бежать через главное.По какой-то причине он ничего не показывает, когда я запускаю код.
Может кто-нибудь сказать мне, посмотрев на мои два класса, почему это ничего не показывает.Может быть, я неправильно называю методы?PizzaOrderingSystem - это мой основной класс, а PizzaMenuView - это класс, который я хотел бы использовать для своего основного.
public class PizzaOrderingSystem extends Application {
private PizzaMenuView pizzaMenuView;
//Creating Stage and making layout for the stage
@Override
public void start(Stage primaryStage){
pizzaMenuView = new PizzaMenuView();
Scene scene = new Scene(pizzaMenuView, 650, 650);
primaryStage.setTitle("Pizza Ordering System");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
