public void accessingJson(JSONObject json) {
  Object invalid = json.get("invalid"); // throws JSONException - "invalid" entry doesn't exists
  String name = json.getString("name"); // name = "John Brown"
  int number = json.getInt("name"); // throws JSONException - "name" entry isn't int
  int age = json.optInt("age", 42); // using default value instead of throwing exception
  JSONArray pets = json.getJSONArray("pets");
  for (int i = 0; i < pets.length(); i++) {
    String pet = pets.getString(i);
  }
}
