A simple test for Retrofit2, RxJava and HTTP error codes

RetrofitErrorCodeTest.java

package com.example;

import okhttp3.ResponseBody;
import retrofit2.Response;
import retrofit2.Retrofit;
import retrofit2.RxJavaCallAdapterFactory;
import retrofit2.http.GET;
import retrofit2.http.Path;
import retrofit2.http.Url;
import rx.Observable;
import rx.Subscriber;

public class RetrofitErrorCodeTest {

    private interface RetrofitInterface {
        @GET("/{code}")
        Observable<Response<ResponseBody>> get(@Path("code") int code);
    }

    public static void main(String[] args) {

        final Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("http://httpstat.us")
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .build();

        final RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);

        retrofitInterface.get(200)
                .subscribe(new Subscriber<Response<ResponseBody>>() {
                    @Override
                    public void onCompleted() {
                        System.out.println("onCompleted");
                    }

                    @Override
                    public void onError(Throwable e) {
                        System.out.println("onError");
                        e.printStackTrace();
                    }

                    @Override
                    public void onNext(Response<ResponseBody> stringResponse) {
                        System.out.println(String.format("onNext: %s", String.valueOf(stringResponse.code())));
                    }
                });

    }
}

Merci for simple and straight code sharing
