Answer 1

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"); 
        }
    }
    }
    }

Answer 2

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/
