Here's an example of writing to and reading from an echoing server.

A simplified excerpt:

Socket echoSocket = null;

PrintWriter out = null;

BufferedReader in = null;

try {

echoSocket = new Socket("taranis", 7);

out = new PrintWriter(echoSocket.getOutputStream(), true);

in = new BufferedReader(new InputStreamReader(

echoSocket.getInputStream()));

} catch (UnknownHostException e) {

System.err.println("Don't know about host: taranis.");

System.exit(1);

} catch (IOException e) {

System.err.println("Couldn't get I/O for "

+ "the connection to: taranis.");

System.exit(1);

}

BufferedReader stdIn = new BufferedReader(

new InputStreamReader(System.in));

String userInput;

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

out.println(userInput);

System.out.println("echo: " + in.readLine());

}
