Answer 1

仿照下面代码：****

    Map map = new HashMap<String, Object>();
map.put("1", "fds");
map.put("2", "valu");
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
list.add(map);
for (Map<String, Object> m : list)
{
  for (String k : m.keySet())
  {
    System.out.println(k + " : " + m.get(k));
  }

}
