This article provides an example of using a proxy to make an HTTP request with the Java programming language.

Java Code

In this example, we use the Residential proxy below:

resi.ipv6.plainproxies.com:8080:customer:product--resi6--pass--nicepass

This proxy is split into four parts separated by colons. We first save the proxy as a string variable, then split it into four parts at each colon and then add it, with authentication, to our proxy dictionary.

import java.io.BufferedReader;  
import java.io.IOException;  
import java.io.InputStreamReader;  
import java.net.*;  
public class Application {  
    private static String proxy_string = "resi.ipv6.plainproxies.com:8080:customer:product--resi6--pass--nicepass";  
    private static String[] proxy_parts = proxy_string.split(":");  
    private static String ip_address = proxy_parts[0];  
    private static int port = Integer.parseInt(proxy_parts[1]);  
    private static String USERNAME = proxy_parts[2];  
    private static String PASSWORD = proxy_parts[3];  
    private static String URL_TO_GET = "http://www.google.com/";  
    public static void main(String[] args) throws IOException {  
        final Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(ip_address, port));  
        Authenticator.setDefault(  
                new Authenticator() {  
                    public PasswordAuthentication getPasswordAuthentication() {  
                        return new PasswordAuthentication(  
                                USERNAME, PASSWORD.toCharArray());  
                    }  
                });  
        final URL url = new URL(URL_TO_GET);  
        final URLConnection urlConnection = url.openConnection(proxy);  
        final BufferedReader bufferedReader = new BufferedReader(  
                new InputStreamReader(urlConnection.getInputStream()));  
        final StringBuilder response = new StringBuilder();  
        String inputLine;  
        while ((inputLine = bufferedReader.readLine()) != null) {  
            response.append(inputLine);  
        }  
        bufferedReader.close();  
        System.out.println(String.format("Response:\n%s", response.toString()));  
    }  
}
