How to get key and value in linkedtreemap$node?

Question

There is a List <Model>, which contains elements of type linkedtreemap, which in turn has a linkedtreemap$node. How do I get to a specific key and value. I get to a specific linkedTreeMap with an elementary loop, but I don't know how to get the key and value further.

for (int i=0; i < models.size(); i++){
    System.out.println(models.get(i));
}

I have attached the complete code below.

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import java.util.List;
    
public class Main {
    
    private final static OkHttpClient HTTP_CLIENT = new OkHttpClient();
    private final static Gson GSON = new Gson();
    
    public static void main(String[] args) throws Exception {
        
        Request request = new Request.Builder()
                .url("https://ghibliapi.herokuapp.com/films")
                .get()
                .build();
        
        Response result = HTTP_CLIENT.newCall(request).execute();
        List<Model> models = GSON.fromJson(result.body().charStream(), List.class);
    
        for (int i=0; i < models.size(); i++){
            System.out.println(models.get(i));
        }
    
    }
}

import java.util.List;
import lombok.Data;
        
@Data
class Model{
    public String id;
    public String title;
    public String original_title;
    public String original_title_romanised;
    public String description;
    public String director;
    public String producer;
    public String release_date;
    public String running_time;
    public String rt_score;
    public List<String> people;
    public List<String> species;
    public List<String> locations;
    public List<String> vehicles;
    public String url;
}
