如何使用ChoiceBox文档中的资源包中的字符串填充javafx？

ChoiceBox<String> choiceBox = new ChoiceBox<>();

ResourceBundle bundle = ResourceBundle.getBundle("your_resource_bundle_name");
List<String> strings = new ArrayList<>(bundle.keySet());

choiceBox.getItems().addAll(strings);

choiceBox.setValue(strings.get(0)); // 设置第一个字符串为默认选项

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ChoiceBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

import java.util.ArrayList;
import java.util.List;
import java.util.ResourceBundle;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        ChoiceBox<String> choiceBox = new ChoiceBox<>();

        ResourceBundle bundle = ResourceBundle.getBundle("your_resource_bundle_name");
        List<String> strings = new ArrayList<>(bundle.keySet());

        choiceBox.getItems().addAll(strings);
        choiceBox.setValue(strings.get(0));

        VBox root = new VBox(choiceBox);
        Scene scene = new Scene(root, 200, 200);

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

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