Answer 1

i created a simple server and a client app. congrats!
but i am unable resolve wether the server is going to accept
more than single client. Not sure what you mean here.... Do you mean "Should I allow it to accept more than one client at a time?" If so, then that's up to you, isn't it?
if not, then should i implement threads to accept more than
one client on my server.If so, you mean. Yes, if you want multiple clients to connect, you have the server socket accept the socket connection from the client and pass that socket to a new thread which handles the connection, then the server socket would be free to accept another connection.
I'm only familiar with the old I/O package, not the New I/O stuff, so this is a bit old school:
ServerSocket ss = new ServerSocket(1234);
while(true) {
   Socket s = ss.accept();
   newClient(s);
private void newClient(final Socket s) {
   Thread t = new Thread() {
      public void run() {
         try {
            BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
            PrintWriter out = new PrintWriter(new OutputStreamWriter(s.getOutputStream()));
            out.println("yes?  what is it?");
            out.flush();
            String line;
            while((line = in.readLine()) != null) {
               out.println("ha ha, you said '" + line + "'");
               out.flush();
         } catch(Exception e) {
            try {
               s.close();
            } catch(Exception e) {
   t.start();
}
