Question

I am sending several messages in my application from client to server one of them is “\r\n.\r\n” how can the server identify this message between others?
I have used equals() method but it did not work:

 is = new BufferedReader(new InputStreamReader(socket
                    .getInputStream()));
 String st = is.readLine();
 if(st.equals("\r\n.\r\n"))
     // ........

Answer 1

is = new BufferedReader(new InputStreamReader(socket
                    .getInputStream()));

is.mark(5);
char[] tmp = new char[5];
is.read(tmp, 0, 5);

if(new String(tmp).equals("\r\n.\r\n"))
   // you have that message
else
   is.reset();
