MAP循环时，需要增删处理方法

LinkedList<Map.Entry<String, JSONArray>> tempList = new LinkedList<Map.Entry<String, JSONArray>>();
tempList.addAll(jfMap.entrySet());
ListIterator<Map.Entry<String, JSONArray>> itor = tempList.listIterator();
Map.Entry<String, JSONArray> entry = null;
while (itor.hasNext()) {
    entry = (Map.Entry<String, JSONArray>) itor.next();
    Object key = entry.getKey();
    if (key.equals(fkztctbm)) {
        JSONArray jsonArray=entry.getValue();
        ftdetail = createJDFV(jsonArray, title, ftdfcode, "", "", fkje.toString(), ftdffzzcode, "");
        JSONArray ftdetail2=(JSONArray)ftdetail.clone();
        jfMap.put(fkztctbm,ftdetail2);
        ftdetail.clear();
        break;
    }
}
