response

JSONObject JObject = new JSONObject(response);
      String getting_data = JObject.getstring("getting data");
    String Todays= JObject.getstring("Todays");
    JsonArray results =JObject.getjsonarray("results");
    for(int i = 0 ; i < results.length(); i++){
     JsonObject resultsobject =results.getjsonobject(i);

    JsonArray worldpopulation 
=resultsobject.getjsonarray("worldpopulation");
         for(int j = 0 ; j < worldpopulation.length(); j++){
     JsonObject worldpopulationobject =worldpopulation.getjsonobject(j);
     JsonObject emptyobject =worldpopulationobject.getjsonobject("");
         String rank=emptyobject .getstring("rank"); 
        String population=emptyobject .getstring("population"); 
        JsonArray flagarray =countrypulation.getjsonarray(flag);
        for(int n = 0 ; n < flagarray.length(); n++){
        JsonObject flagarrayobject =flag1array.getjsonobject(n);
        String flag=flag1arrayobject .getstring("flag"); 
        }

     JsonObject populationobject 
=worldpopulationobject.getjsonobject("population");
         JsonArray emptyarray =JObject.getjsonarray("");
    for(int k = 0 ; k < emptyarray.length(); k++){
        JsonObject emptyarrayobject =emptyarray.getjsonobject(k);
        JsonObject 
countrypulation=emptyarrayobject.getjsonobject("countrypulation");

         String rank1=countrypulation .getstring("rank"); 
        String country=countrypulation .getstring("country"); 
        String population1=countrypulation .getstring("population");
        JsonArray flag1array =countrypulation.getjsonarray(flag);
        for(int m = 0 ; m < flag1array.length(); m++){
        JsonObject flag1arrayobject =flag1array.getjsonobject(m);
        String flag1=flag1arrayobject .getstring("flag"); 
        }
    }
    }
    }

@user2967727 well, response is a string here, in which all the response coming from server is put. He assumes that you have all of that response in string named "response" and then he parse that.

Yes that is how i did.

You parse

{
    ...
}

as JSONObject and

[
    ...
]

as JSONArray. JSONArray contains your objects. From the JSONObject you can retrieve the property values.

JSONArray response = new JSONArray('your json string');

for (int i = 0; i < response.length(); i++) {
    response.getJSONObject(i).getString("property"));
}

BTW your json is invalid, event if you close the missing brackets. Check it here http://jsonlint.com/
