用java，gui实现这样一个代码，建立一个表格，点击表格中的一行，能够展示该行的详细信

以下是一个简单的Java GUI代码示例，用于创建一个表格并在点击表格行时显示详细信息：

import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;

public class TableDemo extends JFrame implements ActionListener {
    private JTable table;
    private JTextArea details;

    public TableDemo() {
        super("Table Demo");

        // Create table data
        Object[][] data = {
            {"John", "Doe", 32},
            {"Jane", "Smith", 28},
            {"Bob", "Johnson", 45},
            {"Lisa", "Williams", 39},
            {"Mark", "Brown", 22},
        };

        // Create table column names
        String[] columnNames = {
            "First Name", "Last Name", "Age"
        };

        // Create table model
        DefaultTableModel model = new DefaultTableModel(data, columnNames);

        // Create table
        table = new JTable(model);

        // Add table selection listener
        table.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
            public void valueChanged(ListSelectionEvent event) {
                // Get selected row index
                int row = table.getSelectedRow();

                // If a row is selected
                if (row >= 0) {
                    // Get data for selected row
                    Object[] rowData = new Object[model.getColumnCount()];
                    for (int i = 0; i < model.getColumnCount(); i++) {
                        rowData[i] = model.getValueAt(row, i);
                    }

                    // Update details text area with selected row data
                    details.setText("Selected Row:\n" +
                                     "First Name: " + rowData[0] + "\n" +
                                     "Last Name: " + rowData[1] + "\n" +
                                     "Age: " + rowData[2]);
                }
            }
        });

        // Create scroll pane for table
        JScrollPane scrollPane = new JScrollPane(table);

        // Create details text area
        details = new JTextArea(5, 20);
        details.setEditable(false);

        // Create panel for details text area
        JPanel detailsPanel = new JPanel(new BorderLayout());
        detailsPanel.setBorder(BorderFactory.createTitledBorder("Details"));
        detailsPanel.add(details, BorderLayout.CENTER);

        // Create main panel for table and details
        JPanel mainPanel = new JPanel(new BorderLayout());
        mainPanel.add(scrollPane, BorderLayout.CENTER);
        mainPanel.add(detailsPanel, BorderLayout.SOUTH);

        // Add main panel to frame
        getContentPane().add(mainPanel);

        // Set window properties
        setSize(400, 300);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
    }

    public void actionPerformed(ActionEvent event) {
        // Handle button click events
    }

    public static void main(String[] args) {
        TableDemo demo = new TableDemo();
        demo.setVisible(true);
    }
}

这个示例创建一个包含名字和年龄的表格，并在底部显示选定行的详细信息。要添加更多列或更改表格数据，只需更改“data”和“columnNames”数组即可。
