为每个按钮单击设置多个标签

Question

我的 javaFx 文件中有 9 个标签和 1 个按钮。我想在每次单击按钮后一一设置标签。我该怎么做？

当我第一次按下按钮时，“数字 1”标签应该改变，当我第二次按下按钮时，“数字 2”标签应该改变，我想改变所有标签

public class Controller {
@FXML
private Label lblone;
@FXML
private Label lbltwo;
@FXML
private Label lblthree;
@FXML
private Label lblfour;
@FXML
private Label lblfive;
@FXML
private Label lblsix;
@FXML
private Label lblseven;
@FXML
private Label lbleight;
@FXML
private Label lblnine;



static int number = 0;
static List<Integer> revealed_no = new ArrayList<>(9);

public void randomNo(){
    number = 1 + (int)(Math.random()*((9-1)+1));
}

public void randomlist(){
    int i = 1;
    while ( !(revealed_no.contains(number)) && (i <= 9)){
        randomNo();
        revealed_no.add(number);
        i++;
    }
    
}}

这是我在控制器中的代码。

请试试这个

public class App1 extends Application {
public static void main(String[] args) {
    launch(args);
}

@Override
public void start(Stage stage) throws Exception {
    stage.setTitle("Greetings");  //creates title

    VBox vBox = new VBox();

    Button btn = new Button("ClicK");
    vBox.getChildren().add(btn);

    Scene scene = new Scene(vBox, 600, 600);
    stage.setScene(scene);

    stage.show();

    btn.setOnAction(event ->{
        Label label = new Label("Some Text");
        vBox.getChildren().add(label);
    });

}
}
