如何在java swing中将文本文件中的数据加载到Jlist？

import javax.swing.*;
import java.awt.*;
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class FileDataLoader extends JFrame {
    private JList<String> dataList;

    public FileDataLoader() {
        setTitle("File Data Loader");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());

        dataList = new JList<>();
        add(new JScrollPane(dataList), BorderLayout.CENTER);

        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }

    public void loadDataFromFile(String filePath) {
        List<String> data = new ArrayList<>();

        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                data.add(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        dataList.setListData(data.toArray(new String[0]));
    }

    public static void main(String[] args) {
        FileDataLoader fileDataLoader = new FileDataLoader();
        fileDataLoader.loadDataFromFile("data.txt");
    }
}
