如何将JTable值从一个帧传递到另一个帧

// 源帧
public class SourceFrame extends JFrame {
    private JTable table;

    public SourceFrame() {
        // 创建JTable并填充数据
        String[] columnNames = {"姓名", "年龄", "性别"};
        Object[][] data = {
            {"张三", 20, "男"},
            {"李四", 25, "女"},
            {"王五", 30, "男"}
        };
        table = new JTable(data, columnNames);

        // 创建保存按钮
        JButton saveButton = new JButton("保存");
        saveButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 获取JTable的数据模型
                DefaultTableModel model = (DefaultTableModel) table.getModel();
                // 将数据模型转换为二维数组
                Object[][] tableData = new Object[model.getRowCount()][model.getColumnCount()];
                for (int i = 0; i < model.getRowCount(); i++) {
                    for (int j = 0; j < model.getColumnCount(); j++) {
                        tableData[i][j] = model.getValueAt(i, j);
                    }
                }
                // 创建目标帧的实例，并传递二维数组
                TargetFrame targetFrame = new TargetFrame(tableData);
                targetFrame.setVisible(true);
            }
        });

        // 将JTable和保存按钮添加到源帧中
        JPanel panel = new JPanel();
        panel.add(new JScrollPane(table));
        panel.add(saveButton);
        add(panel);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        pack();
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new SourceFrame().setVisible(true);
            }
        });
    }
}

// 目标帧
public class TargetFrame extends JFrame {
    private JTable table;

    public TargetFrame(Object[][] tableData) {
        // 创建新的JTable并使用传递的数据
        String[] columnNames = {"姓名", "年龄", "性别"};
        table = new JTable(tableData, columnNames);

        // 将新的JTable添加到目标帧中
        add(new JScrollPane(table));

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        pack();
    }
}
