Example of setting up and using a proxy in Java:

// Setting up a proxy in Java import java.net.Authenticator; import java.net.PasswordAuthentication; import java.net.InetSocketAddress; import java.net.Proxy; import java.net.URL; import java.net.HttpURLConnection; public class ProxyExample { public static void main(String[] args) { // Setting the proxy settings Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxyhost", 8080)); // Optional: Setting up authentication Authenticator.setDefault(new Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication("username", "password".toCharArray()); } }); try { // Creating a URL object URL url = new URL("http://example.com"); // Opening a connection through the proxy HttpURLConnection connection = (HttpURLConnection) url.openConnection(proxy); connection.setRequestMethod("GET"); // Reading the response int responseCode = connection.getResponseCode(); System.out.println("Response Code: " + responseCode); } catch (Exception e) { e.printStackTrace(); } } }
