http get request in java

• In java there are many libraries to verify http get method.one of the library easy to use httpClient.
• An HttpClient can be used to send requests and retrieve their responses. An HttpClient is created through a builder. The builder can be used to configure per-client state, like: the preferred protocol version ( HTTP/1.1 or HTTP/2 ), whether to follow redirects, a proxy, an authenticator, etc. Once built, an HttpClient is immutable, and can be used to send multiple requests.
• In order to use httpClient download httpClient jar from mvn repository or add dependency in your project.

Key notes about GET method:

• GET method is used to retrieve information from server using URI.
• GET request can be cached, bookmarked and remained in browser history.
• GET requests have length restrictions.

import org.apache.http.impl.client.HttpClientBuilder;
import java.util.Scanner;

public class getDemo {
    public static void main(String[] args) throws Exception {
        HttpClient httpclient = HttpClientBuilder.create().build();
    
        HttpGet httpget = new HttpGet("https://reqres.in/api/users?page=2");
    
        System.out.println("Request Type: " + httpget.getMethod());
    
        httpget.addHeader("Content-Type", "application/json");
    
        // Executing the Get request
        HttpResponse httpresponse = httpclient.execute(httpget);
    
        Scanner sc = new Scanner(httpresponse.getEntity().getContent());
    
        // Printing the status line
        System.out.println(httpresponse.getStatusLine());
        while (sc.hasNext()) {
            System.out.println(sc.nextLine());
        }
