Question

im trying to make my ServerSocket communicate with more then one Socket, but i dont know how, so far i realized that invoking serverSocket.accept() would return a socket to communicate between server and the first socket, but then when the second and on are trying to connect to the ServerSocket, it lets them connect, but doesnt get a new socket to communicate with them, so, how do i communicate with the second Socket and on?

Simply put, you need to spawn a new thread if you want to communicate with both sockets at the same time.

ServerSocket ss = new ServerSocket(... params ...);
while(isRunning) {
    Socket socket = ss.accept();
    Runnable r = new SocketHandler(socket); // write the socket handler class
    Thread t = new Thread(r);
    t.start();
} 

Now obviously there are many, many improvements you can make to this. The most obvious would be holding on to the references of r and/or t so you have better/tighter control over them, and the ability to stop them at will. But those features are well beyond the scope of this question.
