Java MCQ: What is the primary use of the Java HTTP Client introduced in Java 11?

Answer:

Explanation:

The primary use of the Java HTTP Client, introduced in Java 11, is to send and receive HTTP requests and responses. The java.net.http.HttpClient class provides a modern, non-blocking API for performing HTTP operations, replacing the older HttpURLConnection class. It supports both synchronous and asynchronous communication and can handle HTTP/1.1 and HTTP/2 protocols.

Here’s a simple example of using the HttpClient to send an HTTP GET request:

import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

public class HttpClientExample {
    public static void main(String[] args) throws Exception {
        HttpClient client = HttpClient.newHttpClient();
        HttpRequest request = HttpRequest.newBuilder()
                                         .uri(new URI("https://www.example.com"))
                                         .build();

        HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());
        System.out.println(response.body());
    }
}

In this example, HttpClient is used to send a GET request to https://www.example.com, and the response body is printed to the console. The HttpClient provides a straightforward and efficient way to interact with HTTP services.
