TCP sockets programming

Here you can find a copy of the source code java files I wrote during last class.

This is the client.

import java.net.Socket;
import java.io.*;
import java.util.Scanner;

class TestTCP {
    public static void main(String args[]) throws  java.net.UnknownHostException, java.io.IOException ,  java.lang.InterruptedException{
        Socket s = new Socket ( "www.upv.es", 80 );
        // Thread.sleep(100000);
        PrintWriter output = new PrintWriter( s.getOutputStream(), true);
        output.println("GET / HTTP/1.0");
        output.println("");
        Scanner input = new Scanner( s.getInputStream());
        while(true) System.out.println(input.nextLine());
    }
}

And this is the server code:

import java.net.*;
import java.io.*;
import java.util.Scanner;

class Server {

    public static void main(String args[]) throws IOException, InterruptedException{
        ServerSocket ss = new ServerSocket(8080);
        while(true) {
            Socket s = ss.accept();    
            Scanner input = new Scanner( s.getInputStream());
            PrintWriter output = new PrintWriter( s.getOutputStream(), true);
            System.out.println(input.nextLine()); // reads a line from the socket (client)
            output.println("Hello client!");
            s.close();
        }
    }
}

Please note that I detailed during the class some DOs and DON'Ts that not necessarily show in my (quick and dirty) code.
