如何在Java中用ComboBox数据填充ArrayList

ComboBox<String> comboBox = new ComboBox<>();
comboBox.getItems().addAll("Item1", "Item2", "Item3");

ArrayList<String> list = new ArrayList<>();

comboBox.setOnAction(e -> {
    String selectedValue = comboBox.getSelectionModel().getSelectedItem();
    list.add(selectedValue);
});

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

import java.util.ArrayList;

public class ComboBoxExample extends Application {
    @Override
    public void start(Stage primaryStage) {
        ComboBox<String> comboBox = new ComboBox<>();
        comboBox.getItems().addAll("Item1", "Item2", "Item3");

        ArrayList<String> list = new ArrayList<>();

        comboBox.setOnAction(e -> {
            String selectedValue = comboBox.getSelectionModel().getSelectedItem();
            list.add(selectedValue);
        });

        VBox vbox = new VBox(comboBox);
        Scene scene = new Scene(vbox, 200, 200);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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