вот пример рабочего клиент сервера

сервер

Код:

package nserver;
import java.io.*;
import java.net.Socket;

public class ServerOne extends Thread
{
    private Socket socket;
    private BufferedReader in;
    private PrintWriter out;
    
    public ServerOne(Socket s) throws IOException
    {
        socket = s;
        in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket
                .getOutputStream())), true);
        start();
    }
    @Override
    public void run()
    {
        try
        {
            while (true)
            {
                String str = in.readLine();
                if (str.equals("END"))
                    break;
                System.out.println("Echoing: " + str);
                out.println(str);
            }
            System.out.println("closing...");
        }
        catch (IOException e)
        {
            System.err.println("IO Exception");
        }
        finally
        {
            try
            {
                socket.close();
            }
            catch (IOException e)
            {
                System.err.println("Socket not closed");
            }
        }
    }
}

Код:

package nserver;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class MServer {
    static final int PORT = 8888;
    public static void main(String[] args) throws IOException
    {
        ServerSocket s = new ServerSocket(PORT);
        System.out.println("Server Started");
        try
        {
            while (true)
            {
                Socket socket = s.accept();
                try
                {
                    ServerOne serverOne = new ServerOne(socket);
                }
                catch (IOException e)
                {
                    socket.close();
                }
            }
        }
        finally
        {
            s.close();
        }
    }
}

клиент

Код:

package nserver;
import java.io.*;
import java.net.InetAddress;
import java.net.Socket;

public class Client {
    public static void main(String[] args) throws IOException
    {
        int PORT = 8888;
        InetAddress addr = InetAddress.getByName(null);
        System.out.println("addr = " + addr);
        Socket socket = new Socket(addr, PORT);
        try
        {
            System.out.println("socket = " + socket);
            BufferedReader in = new BufferedReader(new InputStreamReader(socket
                    .getInputStream()));
            PrintWriter out = new PrintWriter(new BufferedWriter(
                    new OutputStreamWriter(socket.getOutputStream())), true);
            for (int i = 0; i < 10; i++)
            {
                out.println("HELLO " + i);
                String str = in.readLine();
                System.out.println(str);
            }
            out.println("BYE");
        }
        finally
        {
            System.out.println("closing...");
            socket.close();
        }
    }
}
