error when consulting data

Hi, I am doing a query to a database but I have a problem when it returns the result, in the table of the database to which I ask the query there is data that starts with this value 00060306.1000 but when doing the consultation I returned this 636.1 that is, I'm removing the zeros

This is the part where I'm doing that

    public ParameterTable getCatalogoST(List<Map<String, Object>> listexecute){
   ParameterTable catalogoST = new ParameterTable(Arrays.asList(new String[] {"descripcionContocur"}));
   Iterator<Map<String, Object>> iterador = listexecute.iterator();

   while(iterador.hasNext()){
       Map<String, Object> newRow = new HashMap<String, Object>();
       newRow.put("descripcionContocur",iterador.next().get("MC04_CONTOCUR").toString().trim());//:::::::::::::::::::::::::::::::::::::::::::
       catalogoST.add(newRow);
       //LOGGER.info("### resultado  [" +catalogoST+ "]");////////prueba
   }

   return catalogoST;
}
