Name | ### saveJSONArray()
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.

Parameters |
json | JSONArray: the JSONArray to save
filename | String: the name of the file to save to
