Fields contain arrays. Note the following when parsing with gson:

The brown mark is A large object (marked as class A), and the red mark can be marked as an object class B. In this way, when declaring A, List <B> cou_id; it is a member variable, String title; it is a member variable of B and can be parsed by gson. Take a look at the Code:

Type listType = new TypeToken <shortlist <Baby> (){}. getType (); Gson gson = new Gson (); sort list <Baby> babys = gson. fromJson (jsonData, listType); // The User object will be saved to the User list System. out. println (babys. size (); for (Baby baby: babys) {System. out. println (baby );}
