i trying retrieve values : - items: [] such displayruntime: "14", , genre not able reach -

here main pojo class : -

here jackson code trying use : -

@suppresswarnings("rawtypes")     public string[] getshownwdetailsgopherparser (string url) throws jsonparseexception, jsonmappingexception, ioexception{          system.err.println("stage 1");         url jsonurl = new url(url);         objectmapper objmapper = new objectmapper();         objmapper.configure(deserializationfeature.fail_on_unknown_properties, false);         list<assetgen> jsongenshow_1 = objmapper.readvalue(jsonurl, new typereference <list<assetgen>>() {});         list [] shows = new list [jsongenshow_1.size()];          string[] showsarr = new string[jsongenshow_1.size()];         int = 0;         for(assetgen element : jsongenshow_1){             shows[i]=element.getitems().             showsarr[i]=shows[i].tostring();             i++;         }         return showsarr;         } 

need clear solution , new jackson.

items array. think more clear if rename pojo items item.

so value in single item should that:

 for(assetgen element : jsongenshow_1){         list<item> items=element.getitems();         (item item:items) {             //get item value            item.getruntime();            ....         }      }
