import java.net.*;
import java.io.*;

public class ProxyExample {
    public static void main(String[] args) {
        String proxyHost = "your.proxy.host"; // 代理IP地址
        int proxyPort = 8080; // 代理端口
        
        // 创建代理
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, proxyPort));
        
        try {
            // 创建URL对象
            URL url = new URL("http://www.example.com");
            // 打开连接
            HttpURLConnection connection = (HttpURLConnection) url.openConnection(proxy);
            connection.setRequestMethod("GET");
            
            // 获取响应
            int responseCode = connection.getResponseCode();
            System.out.println("响应代码: " + responseCode);
            
            // 读取响应内容
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();
            
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();
            // 输出响应
            System.out.println("响应内容: " + response.toString());
        } catch (IOException e) {
