2. [Code] write operation runable

PW =PW;  This. BR =BR; } @Override Public voidrun () {Try {             while(true) {pw.println (Br.readline ());            Pw.flush (); }        } Catch(IOException e) {e.printstacktrace (); }    }}

3. [Code] Server ServerSocket

Flush () methodPW =NewPrintWriter (NewBufferedWriter (NewOutputStreamWriter (Socket.getoutputstream ())),true); Console=NewBufferedReader (NewInputStreamReader (system.in)); Pool.submit (NewReadthread (BR, "Server")); Pool.submit (NewWritethread (pw,console));  while(true) {Thread.Sleep (10000); }        } Catch(Exception e) {e.printstacktrace (); }finally{System.out.println ("Close in ..."); Try{console.close ();                Br.close ();                Pw.close ();                Socket.close ();            S.close (); } Catch(Exception E2) {} }}}

4. [Code] Client socket
