搜索一个JList

Question

I am looking for a way to create a searchbox linked to a jlist, so that when the user types a sequence of characters, it will search and match to a JList item, then highlight that item. I have created a jtextfield and added a keylistener. This part of the code works properly, but only for the first character the user types. I am trying to expand this to any number of characters the user types. Any ideas how to achieve that? Thank you in advance

String[] feedStrings = {"aaa", "abc", "opo","oiuu"}

JList feedList = new JList(feedStrings);

feedList.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
feedList.setLayoutOrientation(JList.VERTICAL);

feedList.setVisibleRowCount(4);


                JTextField searchbox = new JTextField();
        searchbox.setColumns(8);
        searchbox.setVisible(true);


        searchbox.addKeyListener(new KeyAdapter() {
                 public void keyReleased(KeyEvent e) {

                  String text = "" + e.getKeyChar();
                  StringBuffer buffer = new StringBuffer();
                  buffer.append(text);
                  String strbuf = buffer.toString();

                  int index = feedList.getNextMatch(strbuf, 0, Position.Bias.Forward);
                  System.out.println(index);
                  feedList.setSelectedIndex(index);
            }
      });

Just use the text from the Document. That is another reason to be using a DocumentListener and NOT a KeyListener.

Although I like the suggestion to use a JTable. The Swing tutorial on How to Use Tables even has a working example that shows you exactly how to do this. You can find the link to the tutorial by reading the JTable API.
