List<Map<String,Object>>使用Java代码遍历以获取String，Object的值

List<Map<String,Object>>的结果集怎么使用Java代码遍历以获取String，Object的值？

package excel;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

public class List1

{

public static void main(String[] args)

{

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));

}

}

}

}
