如何将数据添加到JTable

我对Java仍然有点新鲜,对Gui来说还是一个完整的菜鸟。我不能为我的生活找出如何将我的String数组中的数据添加到Jtable中。我试着阅读oracle上的文档但是对于我的特殊情况我没有意义。如果你们能指出我正确的方向,我会很感激。我也是从文件中检索我的数组数据。不确定这是否有所作为。

    public class TemplateGui extends JFrame {
    private JTable tableHotelSecurity, securityFlagsTable;
    private final ButtonGroup buttonGroup = new ButtonGroup();
    private JTextField textField;
    private static String [] sortedRoles_Flags,finalFlagsArr,finalHSArr;
    private static String finalFlags="",finalHS="",column;


    public TemplateGui(){

        super("Galaxy Template Generator V1.0");
        getContentPane().setForeground(new Color(0, 0, 0));
        getContentPane().setLayout(null);
        getContentPane().setBackground(new Color(51, 51, 51));

        JScrollPane scrollPane = new JScrollPane();
        scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
        scrollPane.setBounds(10, 170, 189, 186);
        getContentPane().add(scrollPane);

        JScrollPane scrollPane_1 = new JScrollPane();
        scrollPane_1.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
        scrollPane_1.setBounds(222, 170, 372, 186);
        getContentPane().add(scrollPane_1);

        //radio buttons
        JRadioButton rdbtnNewRadioButton = new JRadioButton("Central User ");
        rdbtnNewRadioButton.setFont(new Font("Tahoma", Font.BOLD, 11));
        rdbtnNewRadioButton.setBackground(Color.WHITE);
        buttonGroup.add(rdbtnNewRadioButton);
        rdbtnNewRadioButton.setBounds(222, 75, 127, 36);
        getContentPane().add(rdbtnNewRadioButton);

        rdbtnPropertyUser.setFont(new Font("Tahoma", Font.BOLD, 11));
        rdbtnPropertyUser.setBackground(Color.WHITE);
        buttonGroup.add(rdbtnPropertyUser);

遵循本教程: http://docs.oracle.com/javase/tutorial/uiswing/components/table.html

主要思想是,swing是建立在MVC架构的原则之上的。这对您来说意味着负责显示表(JTable)的组件以及知道表中的内容(TableModel)的组件是分开的。你不知何故需要将模型传递给表。您可以使用DefaultTableModel,这是您所做的,或者定义您自己的实现接口TableModel的模型。 首先,您需要将一个数组传递给DefaultTableModel的构造函数。 对于后者,您需要实现一些方法 - 其中包括 - 在某些位置查询数据,但只有当开箱即用的东西不适合您时才值得考虑。

关于错误消息的旁注:如果你认真对待编程,不要习惯坏的模式。他们现在看起来似乎更容易,但出于某种原因他们是不明智的。它们通常不能很好地从一个世界规模的项目扩展到由多人开发的完整项目。 Stacktrace是你的朋友。使用记录器而不是sysout。如果你现在习惯了良好的做法,那么从长远来看你会更容易。
