Why do we need displayWeather object when we have currentWeather?

The object currentWeather has every fields set and you can do


and it works as expected. I don't see any reason why you should construct the new CurrentWeather object. After getCurrentDetails(jsonData), the fields must be set or displayWeather does not have any extra/updated information over currentWeather.

I do not think you need to use the overloaded constructor. I believe this way of doing it is correct and more efficient. The Android documents did not specify any reason for doing it using a new object either. Seems like the creators just overlooked this option.
