Question

我试图将我的XML文件数据放在JTable的Movies.java的帮助下，但我不能。它没有向我显示任何类型的错误，但它也没有把它放在面板中。

myXmlFile：

@SuppressWarnings("serial")
public class TabMovieListPanel extends JPanel {


    private static CreateMovieXML moviexml;

    private static JButton del;
    JTable labels;
    private DefaultTableModel model;
    private JTable jTable = new JTable(model);

    private TableRowSorter<TableModel> rowSorter = new TableRowSorter<>(jTable.getModel());

    private JTextField jtfFilter = new JTextField();
    private JButton jbtFilter = new JButton("Filter");


    public void TabMovieListPanel() {

        moviexml = new CreateMovieXML();

        String[] columnNames = { "TITLE", "GENERE", "DURATION", "DIRECTOR", "YEAR" };

            Object[][] data = { { currentValue.getTitle(), currentValue.getGenere(), currentValue.getDuration(),
                    currentValue.getDirector(), currentValue.getYear() } };

我正在尝试将我的XML数据放入jtable中，但它没有在面板上显示任何结果而没有显示任何错误
