Here's some code that connects to google and does a get:
import java.io.*;
import java.net.*;
public class HTTPTest {
    private Socket sock;
    private BufferedReader in;
    private BufferedWriter out;
    private boolean running = false;
    HTTPTest() {
    private void go(String site) {
        try {
            sock = new Socket(site, 80);
            in = new BufferedReader(new InputStreamReader(sock.getInputStream()));
            out = new BufferedWriter(new OutputStreamWriter(sock.getOutputStream()));
            System.out.println("Connected");
            out.write("GET / HTTP/1.1\r\n\r\n");
            out.flush();
            doRead();
        } catch (IOException e) {
            e.printStackTrace();
    private void doRead() {
        running = true;
        String line;
        System.out.println("Read started");
        while (running) {
            try {
                line = in.readLine();
            } catch (IOException e) {
                e.printStackTrace();
                line = null;
            if (line == null) {
                running = false;
            } else {
                System.out.println(line);
        System.out.println("Socket closed");
    public static void main(String [] args) {
        String site;
        if (args.length > 0) {
            site = args[0];
        } else {
            site = "google.ca";
        new HTTPTest().go(site);
}
