Convert List of hashmap to map using streams

    private static Map<String, String> convertListOfHashMap_UsingStream(List<Map<String, String>> input) {
        return input.stream().collect(Collectors.toMap(i -> i.get("attribute_name"), i -> i.get("value")));
    }

    private static Map<String, String> convertListOfHashMap_UsingParallelStream(List<Map<String, String>> input) {
        return input.parallelStream().collect(Collectors.toConcurrentMap(i -> i.get("attribute_name"), i -> i.get("value")));
    }
