Step :- 1:- Use following below given code for Retrofit Class implementation in your application

package siddhu.test.com.myapplication.network;

import retrofit2.Call;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
import retrofit2.http.GET;
import retrofit2.http.Query;
import siddhu.test.com.myapplication.objects.NewsApiArticleResponse;
import siddhu.test.com.myapplication.objects.NewsApiSourcesResponse;

/**

public class NewsAPI {

private static final String API_KEY = "xyz";
private static final String BASE_URL = "https://newsapi.org/v1/";

private static NewsAPIInterface newsAPIInterface;

public static NewsAPIInterface getNewsAPI() {
if (newsAPIInterface == null) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
newsAPIInterface = retrofit.create(NewsAPIInterface.class);
}
return newsAPIInterface;
}

public interface NewsAPIInterface {
@GET("articles?apiKey=" + API_KEY)
Call getArticles(@Query("source") String source, @Query("sortBy") String sortBy);

@GET("sources")
Call getSources();
