in = new BufferedReader (new InputStreamReader (echoSocket.
getInputStream()));
}

catch (UnknownHostException e){
System .err .println("找不到服务器:localhost !");
System .exit(1);

}
String answer=in.readLine();

System .out.println(in.readLine());

BufferedReader stdIn = new BufferedReader(new InputStreamReader(System .in));
String userInput;

while ((userInput = stdIn.readLine())!= null){

out.println(userInput);

System.out .println(in.readLine());
}

out .close();
in.close();
echoSocket .close();

}

}
这是两部分代码，请问哪里出错了？谢谢。
