json - Android Volley JsonArrayRequest send and get List<Object> -

-

i want send jsonarrayrequest linkedlist param , same type result. error 400 means wrong request:

        requestqueue volleyqueue = volley.newrequestqueue(context);         final type type = new typetoken<linkedlist<myclass>>() {}.gettype();         linkedlist<myclass> data = new linkedlist<>();         //populate data...         try {             jsonarrayrequest request = new jsonarrayrequest(                     request.method.get,                     base_url,                     new jsonarray(new gson().tojson(data)),                     new response.listener<jsonarray>() {                         @override                         public void onresponse(jsonarray response) {                             try {                                 processresultdata((linkedlist<myclass>) new gson().fromjson(response.tostring(), type));                             } catch (exception e) {}                         }                     },                     new response.errorlistener() {                         @override                         public void onerrorresponse(volleyerror error) {                          }                     }             );             request.setretrypolicy(new defaultretrypolicy(volley_time_out, defaultretrypolicy.default_max_retries, defaultretrypolicy.default_backoff_mult));             volleyqueue.add(request);         } catch (exception e) {}

on server side it's java spring boot application means:

@restcontroller public class apiclass {     @requestmapping("/base_url")     public linkedlist<myclass> foo(@requestbody linkedlist<myclass> data) {         ...     } }
