使用JSONArray或普通Array来存储/读取数据是否更有效率? [英] Is it more efficient to use a JSONArray or normal Array for storing/reading data?

问题描述

我正在使用一个连接到PHP/MySQL服务器的应用程序，该服务器以JSON格式返回所有内容.例如，用户列表以JSONObject的JSONArray的形式返回.每个对象都包含单个用户的信息(名称，位置，电话号码等).

I'm working with an app that connects to a PHP/MySQL server from which everything is returned in JSON format. For example, a list of users is returned as a JSONArray of JSONObject. Each object contains the individual user's information (name, location, phone number, etc).

在使用这种格式的信息时，将所有内容保留为JSON格式并仅根据需要仅从数组/对象中提取项目的效率更高?还是最好先从JSONArray和包含的对象中提取所有内容以首先构建常规的Array或ArrayList?

In working with information in this format is is more efficient to leave everything in JSON format and only extract items from the array/objects as needed? Or is it better to extract everything from the JSONArrayand included objects to build a regular Array or ArrayList first?

推荐答案

JSONArray在内部使用ArrayList.它只是对ArrayList的包装.所以我说没有区别. JSONObject使用HashMap，因此也没有真正的缺点.

JSONArray internally uses ArrayList. It's just wrapper over ArrayList. So I'd say there is no difference. JSONObject uses HashMap so again no real drawbacks.
