Map<string, list> resultmap;
jsonobject json = Jsonobject.fromobject (RESULTMAP);

for (var key in obj) {//First level loop fetch to each list
     var list = Obj[key];
     for (var student in list) {//second layer loops the object
          alert (list[student].id) in the list;
          Alert (list[student].name);
