for (Iterator it = colecao.iterator(); it.hasNext(); ) {

BlaBleBli obj = (BlaBleBli) it.next();

mestres em java !!!, sequinte :

DefaultMutableTreeNode noRaiz = new DefaultMutableTreeNode("Taxonomy");
     //**
    //*****
    DefaultMutableTreeNode noFilho;
    //******
    for (Iterator i = Log.listSubClasses(); i.hasNext(); ) {
        OntClass c = (OntClass) i.next();

        noFilho = new DefaultMutableTreeNode(c.getLocalName());
        noRaiz.add(noFilho);

        OntClass subLog = ontologia.getOntClass(camNS +c.getLocalName());

         if (subLog.hasSubClass()) { // se tem subitens
          for (Iterator y = subLog.listSubClasses(); y.hasNext(); ) {
              OntClass d = (OntClass) y.next();

              DefaultMutableTreeNode noFilho2 = new DefaultMutableTreeNode(d.getLocalName());
              noFilho.add(noFilho2);
          }
       
       //  i.next(); dar erro, meu objetivo de pular o proximo é para ele não repetir o item do tree que já foi criado como subitem, ou seja, para não criar na raiz também !
       }
