用JavaFX创建2个相互依赖的下拉框的正确方法？

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        ComboBox<String> comboBox1 = new ComboBox<>();
        ComboBox<String> comboBox2 = new ComboBox<>();

        // 设置comboBox1的选项
        comboBox1.setItems(FXCollections.observableArrayList("选项1", "选项2", "选项3"));

        // 绑定comboBox2的选项到comboBox1的值
        comboBox2.itemsProperty().bind(comboBox1.valueProperty().asString().concat("的选项"),
                FXCollections.observableArrayList("选项1", "选项2", "选项3"));

        VBox root = new VBox(comboBox1, comboBox2);
        Scene scene = new Scene(root, 200, 200);

        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
