java8 两个List对象合并和List的转换成Map

public static void main(String[] args) {

        List<String> idList = new ArrayList<>(Arrays.asList("姓名", "性别"));
        List<String> nameList = new ArrayList<>(Arrays.asList("杰克", "男"));

        Map<String,String> listMap = idList.stream().collect(Collectors.toMap(key->key, key->nameList.get(idList.indexOf(key))));
        System.out.println(listMap.toString());
    }
