So I already succeed with one Json to get it all worked. Now I have another class where I want to get only one attribute. I have now a moviedatabase class (which work with JSON and gets all the information) and now I want to add a Trailer which is from Youtube API. so basically I need it to be added into the same JSON to make it easier for me in the future to get it into a HTML. the only problem is I cant get it work. I get a syntax error JSON when using this method.
EDIT CODE 1.1:
Youtube attribute:
public class FilmAttribut {
private String title = "";
private String release = "";
private int vote = 0;
private String overview = "";
private String poster = "";
private String trailer = "";
// getters + setters stripped
}
Youtube class:
public class Youtube {
FilmAttribut movie = new FilmAttribut();
public void search(String trailer, FilmAttribut in) {
HttpResponse<JsonNode> response;
try {
response = Unirest.get("https://www.googleapis.com/youtube/v3/search?key=[app key here]&part=snippet")
.queryString("q", trailer + " trailer")
.asJson();
JsonNode json = response.getBody();
JSONObject envelope = json.getObject();
JSONArray items = envelope.getJSONArray("items");
in.setTrailer("https://youtu.be/" + items.getJSONObject(0).getJSONObject("id").getString("videoId")); //Gives me error here
}
catch (JSONException e) {
e.printStackTrace();
} catch (UnirestException e) {
e.printStackTrace();
}
return null;
}
}
and main method
public class WebService {
public static void main(String[] args) {
setPort(1337);
Gson gson = new Gson();
Youtube yt = new Youtube();
MovieDataBase mdb = new MovieDataBase();
get("/search/:movie", (req, res) -> {
String titel = req.params(":movie");
FilmAttribut film = mdb.searchMovie(titel);
yt.search(titel, film);
String json = gson.toJson(film);
return json;
});
So I think the problem is that you can't have two gson.toJson(film) + gson.toJson(trailer);
Because it makes the JSON twice, where one time is for the film (aka. movie) and then a new json is created with trailer which make the syntax error.
So my real question is, is it possible to have another class like I have now youtube. to send the information to a attribute class where I have all my attributes and then run it in main-method so that I can get all the JSON in one JSON.

If I did understand well what you are asking, yes you can, but I would do something like that instead:
public void search(String trailer, FileAttribut in) {
// fetch the trailer from youtube (NB: you should use getters/setters, not public fields)
in.setTrailer("https://youtu.be/" + items.getJSONObject(0).getJSONObject("id").getString("videoId"));
}
and:
FilmAttribut film = mdb.searchMovie(titel);
yt.search(titel, film); // pass "film" to "fill" its trailer
return gson.toJson(film);
OR
public String search(String trailer) {
// fetch the trailer from youtube
return "https://youtu.be/" + items.getJSONObject(0).getJSONObject("id").getString("videoId");
}
and:
FilmAttribut film = mdb.searchMovie(titel);
film.setTrailer(yt.search(titel));
return gson.toJson(film);
