将已解析的数组列表数据存储在JTable中

Question

我的代码无效。我想在JTable中解析我的rss新闻，但是我不能这样做，因为我不知道如何为JTable制作数据代码

public class News { 
    public static String[] col = {"№", "Smi", "Title", "Link", "Description"};
    public static String[][] data;

public static void main(String[] args) throws IOException {
    new Window();
}

public static void readRSS() {
            try {
                for (i = 0; i < sources.length; i++) {
                    RSSFeedParser parser = new RSSFeedParser(sources[i]);
                    if (isStop.get()) return;
                    Feed feed = parser.readFeed();
                    for (FeedMessage message : feed.getMessages()) {
                        j++;
                        if (message.toString().indexOf(Window.find_word) >= 1) {                                   
                                titleTable =  message.getTitle();
                                linkTable =  message.getLink();
                                descrTable = message.getDescription();

                            data = new String[feed.getMessages().size()][col.length];
                            for (int x = 0; x <  feed.getMessages().size(); x++){
                            data[x][0] = String.valueOf(x);
                            data[x][1] = smi;
                            data[x][2] = titleTable;
                            data[x][3] = linkTable;
                            data[x][4] = descrTable;
                            }

带有Window的另一个类。当我使表格=新的JTable（News.data，News.col）; -我有NullPointerException ..

public class Window extends JFrame {
//Table
        JScrollPane scrollPane = new JScrollPane();
        scrollPane.setBounds(10, 40, 874, 300);
        getContentPane().add(scrollPane);

        String[][] data = { {null, null, null, null, null}                            
                            };
        table = new JTable(data, News.col);
        table.setBackground(new Color(194, 239, 194));
        scrollPane.setViewportView(table);

这是我从rss来源获取数据的数组。

public class Feed {
    final List<FeedMessage> entries = new ArrayList<FeedMessage>();

    public Feed(String title, String link, String description) {
    }
    public List<FeedMessage> getMessages() {
        return entries;
    }
}

class FeedMessage {
    String title;
    String link;
    String description;

    public void setTitle(String title) {
        this.title = title;
    }
    public void setLink(String link) {
        this.link = link;
    }
    public void setDescription(String description) {
        this.description = description;
    }

    public String getLink() {
        return link;
    }
    public String getTitle() {
        return title;
    }
    public String getDescription() {
        return description;
    }

非常感谢！！！ ：））

        JScrollPane scrollPane = new JScrollPane();
        scrollPane.setBounds(10, 40, 874, 300);
        getContentPane().add(scrollPane);

        String[] columns = {"Title", "Author", "Description", "Date", "Feed"};
        model = new DefaultTableModel(null, columns);
        table = new JTable(model);
        scrollPane.setViewportView(table);

String[] row = new String[]{
                               message.getTitle(),
                               message.getLink(),
                               message.getDescription()
                               };
                               Window.model.addRow(row);
