Jtree: "check if tree node is a folder" not wrkin

Question

Hi, I have a JTree and If a folder does not has any file, it displays as file not folder. Is there any way to fix it. I want to represent an empty folder as folder not file. here is the code. Thanks for help.
if(!f.isDirectory()) {
     System.out.println("FILE - " + f.getName());
     DefaultMutableTreeNode child = new DefaultMutableTreeNode(f.getName());
     node.add(child);
     else {
     DefaultMutableTreeNode child = new DefaultMutableTreeNode(f.getName());
          node.add(child);
     File fList[] = f.listFiles();
     for(int i = 0; i < fList.length; i++)
     getList(child, fList);

Sorry for not formatting the code:
here is the code again:
public void getDirectories()
     getList(root, new File("c:/FIST/Projects/"));
       KeyStroke ks = KeyStroke.getKeyStroke("ctrl A");
       tree.getInputMap().put(ks, "none");
public void getList(DefaultMutableTreeNode node, File f)
     if(!f.isDirectory())
DefaultMutableTreeNode child = new DefaultMutableTreeNode(f.getName());
            int i=child.getLevel();
            if(i==0)
                node.add(child);
     else {
              DefaultMutableTreeNode child = new DefaultMutableTreeNode(f.getName());
             node.add(child);
              File fList[] = f.listFiles();
              for(int i = 0; i  < fList.length; i++)
                  getList(child, fList);
