How to read bytes from a socket into a buffer in java and then display it on the screen?

Question

Java

My code:

Socket s = new Socket(host, Integer.parseInt(port));

        PrintWriter out = new PrintWriter(s.getOutputStream(),true);
        BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));

        out.println("tyda"); 

        char[] buff = new char[1024];
        in.read(buff,0,buff.length);

        System.out.println(buff);

Doesn't work, as you can see. how to output this buffer to stdout to read the response?
