ELABORACIÓN DE UN CHAT
1.- Se creo un servidor para poder hacer la comunicación entre varios clientes en la red
import java.net.*;
import java.io.*;
import java.util.*;
public class ChatServidor {
public ChatServidor() throws IOException {
Vector x = new Vector();
//Creamos un servidor
ServerSocket server = new
ServerSocket(20,2,InetAddress.getByName("192.168.0.9"));
while (true) {
Socket client = server.accept ();
System.out.println("Entro " + client.getInetAddress());
x.add(client.getInetAddress());
Sirvo c = new Sirvo(client,x);
c.start ();
}
}
public static void main (String args[]) throws IOException {
new ChatServidor();
}
}
import java.net.*;
import java.io.*;
import java.util.*;
public class Sirvo extends Thread {
protected Socket s;
protected DataInputStream i;
protected DataOutputStream o;
Vector y = new Vector();
public Sirvo(Socket s, Vector x) throws IOException {
this.s = s;
i = new DataInputStream (new BufferedInputStream (s.getInputStream ()));
o = new DataOutputStream (new BufferedOutputStream (s.getOutputStream ()));
y = x;
}
protected static Vector handlers = new Vector ();
public void run () {
String name = s.getInetAddress ().toString ();
String Listado="";
try {
for (int i=0; i < y.size() ; i++)
Listado=Listado+y.get(i)+"\n";
handlers.addElement (this);
broadcast ("->" + Listado);
while (true) {
String msg = i.readUTF ();
broadcast (name + " - " + msg);
}
} catch (IOException ex) {
ex.printStackTrace ();
} finally {
handlers.removeElement (this);
y.remove(name);
Listado="";
for (int i=0; i < y.size() ; i++)
Listado=Listado+y.get(i)+"\n";
broadcast ("<-" + Listado);
try {
s.close ();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
protected static void broadcast (String message) {
synchronized (handlers) {
Enumeration e = handlers.elements ();
while (e.hasMoreElements ()) {
Sirvo c = (Sirvo) e.nextElement ();
try {
synchronized (c.o) {
c.o.writeUTF (message);
}
c.o.flush ();
} catch (IOException ex) {
c.stop ();
}
}
}
}
}
2.- Posteriormente se tuvo que crear un código de interfaz para poderse comunicar en un ambiente
grafico para cada uno de los clientes que se conecten al servidor.

3.- si uno de los clientes decide desconectarse en el otro le saldrá un mensaje del equipo que salio…
