Question

我从事股票市场项目。我想制作显示股票市场图表和新闻的桌面应用程序。到目前为止，我已经制作了一个主框架（类），它有RSS，第二个是applcationframe，显示蜡烛图表（2类）。我想把图表放到我的主框架中。如何将它放入我的主框架/（或者如何将应用程序框架调用到框架中）。我将真正感谢所有的建议。这是主框架的代码：



import java.awt.BorderLayout;
public class Boeing extends JFrame {

    private JPanel contentPane;

    /**
     * Launch the application.
     */

                try {
                    Boeing frame = new Boeing();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }

    }

            BufferedReader in = new BufferedReader(new InputStreamReader(rssUrl.openStream()));
            String sourceCode = "";
            String line;
            while((line = in.readLine())!=null) {
                if (line.contains("<title>")){
                    int firstPos = line.indexOf("<title>");
                    String temp = line.substring(firstPos);
                    temp = temp.replace("<title>", "");
                    int lastPos = temp.indexOf("</title>");
                    temp = temp.substring(0,lastPos);
                    sourceCode += temp + "\n" + "\n";
                }

如果我想创建一个在主框架中显示图表的方法，怎么办呢？
