Java 试图将项目从txt文件添加到jList

Java 试图将项目从txt文件添加到jList,java,swing,netbeans,jframe,jlist,Java,Swing,Netbeans,Jframe,Jlist,我有下面的try-catch块,它在单击按钮时执行 try { //picking up the file I want to read in BufferedReader in = new BufferedReader(new FileReader("C:\\users\\me\\desktop\\blah.txt")); String line; try { //read through

我有下面的try-catch块,它在单击按钮时执行

  try {
//picking up the file I want to read in
 BufferedReader in = new BufferedReader(new FileReader("C:\\users\\me\\desktop\\blah.txt"));
 String line;                                           
 try {
    //read through the file until there is nothing left and add each line to list
         while((line = in.readLine()) != null){  
            jList1.add(line, jList1);
                    }

               } catch (IOException ex) {
                    Logger.getLogger(Frame2.class.getName()).log(Level.SEVERE, null, ex);
           }
      } catch (FileNotFoundException ex) {
                Logger.getLogger(Frame2.class.getName()).log(Level.SEVERE, null, ex);
  }
我可以成功地
System.out.println(line)
,所以我知道有些东西工作正常。我无法用文本文件中的行填充列表。上面的代码告诉我我
无法将容器父容器添加到self。

试图找到更多的信息只会让我更加困惑。我遇到过一些地方说jLists比这更复杂?

你真的做不到:
再次阅读此行:
jList1.add(行,jList1)存在许多错误,太多,无法对所有错误进行评论:

(一)

(二)

(三)

(四)

必须是
FileReader
阅读教程。这是基本的东西。可能是重复的
    BufferedReader in = null;
    String line;
    DefaultListModel listModel = new DefaultListModel();
    try {
        in = new BufferedReader(new FileReader("C:\\users\\me\\desktop\\blah.txt"));
        while ((line = in.readLine()) != null) {
            listModel.addElement(line); //(String.valueof(line));
        }
    } catch (IOException ex) {
        Logger.getLogger(Frame2.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        if (in != null) {
            in.close();
        }
    }
    JList jList1 = new JList(listModel);
