Triggering asynchronous GET request is a three-step job, as follows:

1. Create a new HttpClient object (java.net.http.HttpClient):

HttpClient client = HttpClient.newHttpClient();

HttpRequest request = HttpRequest.newBuilder()  .uri(URI.create("https://reqres.in/api/users/2"))  .build();

For setting the URI, we can call the HttpRequest.newBuilder(URI) constructor or call the uri(URI) method on the Builder instance (like we did previously).
