使用Stream流遍历Map获取键值对并转换为List

List<Map.Entry<String, List<List<Object>>>> entryList = new ArrayList<>(scoreDetailMap.entrySet());

List<String> sheetNames = entryList.stream() .map(Map.Entry::getKey) .collect(Collectors.toList());

List<List<List<Object>>> contents = entryList.stream() .map(Map.Entry::getValue) .collect(Collectors.toList());

entryList.forEach(entry -> System.out.println("方法三的key为：" + entry.getKey() + ", value为：" + entry.getValue()));
