Re: Socket problem: read & write to same socket
Liyaohua, please realize the reason is that you use a BufferedWriter,
and you close the socket directly. The BufferedWriter has no way to
hook into that close and flush itself. out.close instead of s.close()
would achieve the same thing. Beware though that sometimes you don't
want to close a socket just because you're done with the OutputStream
(or InputStream).
Sorry to top post but I'm afraid the OP might not see this comment
otherwise...

I want to establish connection to a server(written by myself in Go language), read from socket, and then write into socket.
The connection can be established, and it reads correctly. But after that and when I want to write to socket, it closes the connection. I used wireshark to listen to the packets. I saw my program sent a FIN to the server side. So the server receives nothing.
Note that the server side only sends one line into socket.
I later wrote a server in Java and a client in Go. They work fine in both read and write.

//PrintWriter out = null;
try {
s = new Socket("127.0.0.1", 9999);
in = new BufferedReader(new InputStreamReader(s.getInputStream()));
//out = new PrintWriter(s.getOutputStream(), false);
out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
} catch (UnknownHostException e) {
System.err.println("Unknown host");
System.exit(0);
} catch (IOException e) {
System.err.println("IO error");
System.exit(1);
}
String msg = "";
msg = in.readLine();
System.out.println(msg);
out.write("\"hi, socket\"");
Try:
out.flush();
here.
s.close();
}
}
