java - Does closing the BufferedReader/PrintWriter close the socket connection?

Question

I have an application that uses simple sockets to pass some characters between two systems. I have my java application running as a server. I establish a connection fine, and even pass one message. However, after one message has been sent my connection closes.

From what I can tell it appears as if on closing the printWriter and bufferedReader the socket itself is being closed?! This is bad, as I have multiple messages to send on the same connection.

printWriter = new PrintWriter(theServer.getClientSocket().getOutputStream());
bufferedReader = new BufferedReader(new InputStreamReader(theServer.getClientSocket().getInputStream()));


printWriter.println("the line");

printWriter.close(); //Closing on these lines?
bufferedReader.close(); //Closing on these lines?

Am I full of it? How do I maintain this connection in Java?

Answer 1

Yes, closing any Writer/Reader will close all other Writers and Readers that they wrap. Don't close it until you are ready to close the underlying socket.
