Java Coding Problems

New User to JSON request

The following solution creates a new user (the response status code should be 201):

Data data = new Data();data.setId(10);data.setFirstName("John");data.setLastName("Year");data.setAvatar("https://johnyear.com/jy.png");User newUser = new User();newUser.setData(data);HttpRequest requestPost = HttpRequest.newBuilder()  .header("Content-Type", "application/json")  .uri(URI.create("https://reqres.in/api/users"))  .POST(HttpRequest.BodyPublishers.ofString(jsonb.toJson(user)))  .build();HttpResponse<Void> responsePost = client.send(  requestPost, HttpResponse.BodyHandlers.discarding());int sc = responsePost.statusCode(); // 201

Note that we ignore any response body via HttpResponse.BodyHandlers.discarding().
