saveJSONArray()保存JSON数组

Examples

String[] species = { “Capra hircus”, “Panthera pardus”, “Equus zebra” };

String[] names = { “Goat”, “Leopard”, “Zebra” };

JSONArray values;

void setup() {

values = new JSONArray();

for (int i = 0; i < species.length; i++) {

JSONObject animal = new JSONObject();

animal.setInt(“id”, i);

animal.setString(“species”, species[i]);

animal.setString(“name”, names[i]);

values.setJSONObject(i, animal);

}

saveJSONArray(values, “data/new.json”);

}

// Sketch saves the following to a file called “new.json”:

// [

// {

// “id”: 0,

// “species”: “Capra hircus”,

// “name”: “Goat”

// },

// {

// “id”: 1,

// “species”: “Panthera pardus”,

// “name”: “Leopard”

// },

// {

// “id”: 2,

// “species”: “Equus zebra”,

// “name”: “Zebra”

// }

// ]

Description

Writes the contents of a JSONArray object to a file. By default, this file is saved to the sketch’s folder. This folder is opened by selecting “Show Sketch Folder” from the “Sketch” menu.

Alternatively, the file can be saved to any location on the computer by using an absolute path (something that starts with / on Unix and Linux, or a drive letter on Windows).

All files loaded and saved by the Processing API use UTF-8 encoding.

将 JSONArray 对象的内容写入文件。默认情况下, 此文件保存到草绘的文件夹中。通过从 “草绘” 菜单中选择 “显示草图文件夹” 打开此文件夹。

或者, 该文件可以通过使用绝对路径 (在 unix 和 linux 上启动的东西, 或 windows 上的驱动器号) 保存到计算机上的任何位置。

处理 api 加载和保存的所有文件都使用 UTF-8 编码。
