updateDisplay() gives a nullpointer exception even though the Weather object is populated with json data from the api ca

ShowWeather() works with all weather data but updateWeather() doesn't

                    });

                } else {
                    network.alertError();
                }
            } catch (IOException | JSONException e) {
                Log.e("Network Response", "Exception Caught", e);
            }

private void updateWeather() { temperature.setText(String.valueOf(currentWeather.getTemperature())); }

private void showWeather() {
   Log.v("Weather", currentWeather.spit());
}
