loadJSONObject()

Loads a JSON from the data folder or a URL, and returns a JSONObject.

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

• // The following short JSON file called "data.json" is parsed 
  // in the code below. It must be in the project's "data" folder.
  
  /*  
    {
      "id": 0,
      "species": "Panthera leo",
     "name": "Lion"
    }
  */
  
  JSONObject json;
  
  void setup() {
  
    json = loadJSONObject("data.json");
  
    int id = json.getInt("id");
    String species = json.getString("species");
    String name = json.getString("name");
  
    println(id + ", " + species + ", " + name);
  }
  
  // Sketch prints:
  // 0, Panthera leo, Lion
