[{"appointtime":"2015-12-31?00","count":0},{"appointtime":"2015-12-31?01","count":0},{"appointtime":"2015-12-31?02","count":0}] [["2015-12-31?00",0],["2015-12-31",01],["2015-12-31?02",0]]

你好小Song

Map<Object,Object>?map?=?new?HashMap<>();
for(Map<String,Object>?m:list){
????map.put(m.get("appointtime"),m.get("count"));
}
System.out.println(map);

另:?樓主題目的結(jié)果數(shù)據(jù)是不是寫錯(cuò)了,?應(yīng)該為[["2015-12-31?00",0],["2015-12-31?01",0],["2015-12-31?02",0]]

烏云下的風(fēng)
System.out.println(map); 打印結(jié)果 {2015-12-31 00=0, 2015-12-31 01=0, 2015-12-31 02=0} 你的格式錯(cuò)了我把它放到數(shù)組中了格式就對(duì)了 [["2015-12-31 00",0],["2015-12-31 01",0],["2015-12-31 02",0]]
