JSONArray jsonArray = JSON.parseArray(text);2. jdk 1.8
jsonArray = IntStream.rangeClosed(0, jsonArray.size() - 1).mapToObj(jsonArray::getJSONObject).sorted(Comparator.comparing((JSONObject jsonObject) -> jsonObject.getString("time")).thenComparing(jsonObject -> jsonObject.getString("value"))).distinct().collect(Collectors.toCollection(JSONArray::new));先按照time再按照value排序；
3.输出查看结果
jsonArray.forEach(System.out::println);本回答被题主选为最佳回答 , 对您是否有帮助呢?评论 打赏解决 2无用举报 分享
