使用JavaFX时发生奇怪的错误

Question

我试图用javafx做一个tic tac toe游戏但突然添加了if程序停止正常工作后如果[if(chiediConferma)]我删除了所述错误，编译器在那里给我错误没有脚本中的任何错误。

现在让我解释一下程序如何首先通过一个确认框，程序会询问玩家他们是否想要玩tic tac toe然后如果玩家选择"si"（"yes" in italian）他们的窗口随着游戏的出现，如果他们选择"no"，程序就会结束。当我添加说如果游戏窗口显示为空白，当我点击它时，光标会转到加载图标，就像这样，直到出现"X stopped working"弹出窗口，你对这是什么问题有所了解吗？

（对不起破解的语法和英语）

这是菜单类：

    Label Messaggio = new Label();

    Button si = new Button("Si");
    Button no = new Button("No");
    si.setOnAction(e -> {
       scelta = true;
       menu.close();
    });
    no.setOnAction(e -> {
       scelta = false;
       menu.close();
    });

    GridPane selezione = new GridPane();
    selezione.setPadding(new Insets(10,10,10,10));
    selezione.setVgap(10);
    selezione.setHgap(10);

    selezione.setConstraints(Messaggio, 1,0);
    selezione.setConstraints(si, 0,1);
    selezione.setConstraints(no, 2,1);

    selezione.getChildren().addAll(Messaggio, si, no);

    Scene SceneMenu = new Scene(selezione, 1000, 600);
    menu.setTitle(titolo);

    menu.setScene(SceneMenu);

    menu.showAndWait();
    return scelta;
}

}
