Creating dynamic JTree from absolute file path

private void createNodes(DefaultMutableTreeNode top) {
    List <String> files = new ArrayList<String>();      
    //getFileNames() returns array list of file name with complete path
    //eg C:/lanceTest1/directory1/sample.txt
    files = getFileNames();     
    DefaultMutableTreeNode node = null;
    for (String fileName : files) {
        node = new DefaultMutableTreeNode(fileName);
        top.add(node);               
    }
}

Above function creates below window.
