If the return value of the API is jsonarray, I can easily use arraylist to store and use the value. However, I do not know how to store the value if the API return value consists of just multiple objects.

//if return values are array
public interface StockApi {

    @GET("stock/{symbol}/financials")
    Observable<Financials> getFinancial(@Path("symbol") String symbol);
}

public class Financials {

    @Expose
    public String symbol;

    @Expose
    public List<Financial> financials;

}

//

import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

public class StockService {
private static StockService instance;
private static String BASE_URL = "https://api.iextrading.com/1.0/";
private Retrofit retrofitInstance;
private StockApi stockApi;

public StockService() {
    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new 
OkHttpClient.Builder().addInterceptor(interceptor).build();

    retrofitInstance = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create())
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .build();

    stockApi = retrofitInstance.create(StockApi.class);
}

public StockApi getStockApi() {
    return stockApi;
}

public static StockService getInstance() {
    if (instance == null) {
        instance = new StockService();
    }
    return instance;
}
}

but below return values are just consist of Object.
