Problems with JTree

[LianaN]

Hi again!

I would like once again to ask your professional feedback. So, I have JTree that displays the content of "D:\\docmngsyst\\docs". I cannot find the answer for the following question:
*) How to make my tree opened. I mean that initially I see only root node without any other nodes. But I need to display whole tree (at least two levels).

Thanks for any idea or a link to tutorial!

        DefaultMutableTreeNode master = new DefaultMutableTreeNode("Documents");
        tree = new JTree(master);
        listAllFiles("D:\\docmngsyst\\docs",  master, true);

    public static void listAllFiles(String directory, DefaultMutableTreeNode parent, Boolean recursive) {
         File [] children = new File(directory).listFiles();
         for (int i = 0; i < children.length; i++) {
                   DefaultMutableTreeNode node = new DefaultMutableTreeNode(children[i].getName());
                   if (children[i].isDirectory() && recursive) {
                         parent.add(node);
                         listAllFiles(children[i].getPath(), node, recursive);
                   } else if (!children[i].isDirectory()){
                   parent.add(node);
              }
         }
    }

Uf, it was a bit stupid question. I just had to change two lines of code to solve the problem:

        DefaultMutableTreeNode master = new DefaultMutableTreeNode("Documents");
        listAllFiles("D:\\docmngsyst\\docs",  master, true);
        tree = new JTree(master);

Sorry.
