哪位高手能给小弟我解释上，这个PrintWriter把SSLSocket输出到了哪_J2EE

谁能给我解释下，这个PrintWriter把SSLSocket输出到了哪？
如下代码所示,SSLSocket是接受到的信息包。bis和bos是不是分别接受信息和把信息返回给发送方？比如SSLSocket是从192.168.0.2上发过来的，bis接受发送的数据，bos将信息发送回192.168.0.2？

Java code

SSLSocket socket = (SSLSocket) serverSocket.accept();//接受信息包InputStream input = null;OutputStream output = null;BufferedReader bis = null;PrintWriter bos = null;input = socket.getInputStream();output = socket.getOutputStream();bis = new BufferedReader(new InputStreamReader(input,"utf-8"));bos = new PrintWriter(new BufferedWriter(new OutputStreamWriter(output, "utf-8")));

------解决方案--------------------
LZ自己都给出答案了，bis接受192.168.0.2发过来的数据，bos将信息发送回192.168.0.2
