title: The application does not terminate if you use Retrofit
body: <p>Good day to all! Please tell me what needs to be done so that the application completes its work when using Retrofit?</p>
  <pre><code>public static void main(String[] args) throws IOException {
  
      NetworkResponse networkResponse = new NetworkResponse(API_KEY);
      Call&lt;YouTubeVideo&gt; YouTubeVideoCall = networkResponse.getVideoInformation(MUSIC);
      Response&lt;YouTubeVideo&gt; response = YouTubeVideoCall.execute();
      YouTubeVideo youTubeVideo = response.body();
      System.out.println(youTubeVideo);
  }
  </code></pre>
  <p>The application outputs data, but the work is not completed:(</p>
