Here is my code for JTree

Code:

---

    DefaultMutableTreeNode node;
    File[] roots = File.listRoots();
    for (int k=0; k<roots.length; k++)
    {
      node = new DefaultMutableTreeNode(new IconData(ICON_DISK, null, new FileNode(roots[k])));

      top.add(node);
      node.add( new DefaultMutableTreeNode(new Boolean(true)));
    }

    m_model = new DefaultTreeModel(top);
    m_tree = new JTree(m_model);
    m_tree.putClientProperty("JTree.lineStyle", "Angled");

    TreeCellRenderer renderer = new
    IconCellRenderer();
    m_tree.setCellRenderer(renderer);

    m_tree.addTreeExpansionListener(new
    DirExpansionListener());

    m_tree.addTreeSelectionListener(new
    DirSelectionListener());

    m_tree.getSelectionModel().setSelectionMode(
    TreeSelectionModel.SINGLE_TREE_SELECTION);
    m_tree.setShowsRootHandles(true);
    m_tree.setEditable(false);

    final JScrollPane s = new JScrollPane();
    s.getViewport().add(m_tree);
