如何通过另一个线程更新我的jLabel？

import javax.swing.*;
import java.awt.*;
import java.util.List;

public class UpdateLabelExample {

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            JFrame frame = new JFrame("Update JLabel Example");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setLayout(new FlowLayout());

            JLabel label = new JLabel("Initial Text");
            frame.add(label);

            JButton updateButton = new JButton("Update");
            updateButton.addActionListener(e -> {
                // 创建并执行SwingWorker线程
                SwingWorker<String, Integer> worker = new SwingWorker<String, Integer>() {
                    @Override
                    protected String doInBackground() throws Exception {
                        // 模拟耗时操作
                        Thread.sleep(2000);
                        return "Updated Text";
                    }

                    @Override
                    protected void done() {
                        try {
                            // 获取SwingWorker的返回结果并更新jLabel
                            String updatedText = get();
                            label.setText(updatedText);
                        } catch (Exception ex) {
                            ex.printStackTrace();
                        }
                    }
                };

                worker.execute(); // 执行SwingWorker线程
            });
            frame.add(updateButton);

            frame.setSize(300, 200);
            frame.setVisible(true);
        });
    }
}
