Libgdx Json Parsing From An Api

I'm trying to parse a JSON returned by OpenWeatherMap API, specifically this. I'm using the approach suggested in this post, that is create classes with class variables with names

Solution 1:

So, there were few solutions:

• Use an ObjectMap (link, at the very end)
• Parse it myself (the last resort)

• or the one I'm currently employing successfully:

  /*...*/Jsonjson=newJson();
  StringjsonStr=/* JSON here */
  jsonStr = jsonStr.replace("\"3h\"", "\"_3h\"");
  JSONWrapperjsonWrapper= json.fromJson(JSONWrapper.class, jsonStr);
  /*...*/

Accessing values:

double windSpeed = jsonWrapper.wind.speed;

And the wrapper class:

import java.util.ArrayList;

publicclassJSONWrapper{
    Coord coord;
    ArrayList<Weather> weather;
    String base;
    MainJ main;
    Wind wind;
    Clouds clouds;
    Rain rain;
    Snow snow;
    int dt;
    Sys sys;
    int id;
    String name;
    int cod;
    String message;
    Visibility visibility;
}

classWeather{
    int id;
    String main;
    String description;
    String icon;
}

classCoord{
    double lon;
    double lat;
}

classVisibility{
    String value;
}

classMainJ{
    double temp;
    int pressure;
    int humidity;
    double temp_min;
    double temp_max;
}

classWind{
    double speed;
    int deg;
}

classClouds{
    int all;
}

classSnow{
    int _3h;
}

classRain{
    int _3h;
}

classSys{
    int type;
    int id;
    double message;
    String country;
    int sunrise;
    int sunset;
}
