24EchoTCPClient client = new EchoTCPClient(); BufferedReader input, echoInput; PrintWriter echoOutput; String line; String host = "127.0.0.1"; // We want to timeout if a response takes longer than 60 seconds client.setDefaultTimeout(60000); client.connect(host); System.out.println("Connected to " + host + "."); input = new BufferedReader(new InputStreamReader(System.in)); echoOutput = new PrintWriter(new OutputStreamWriter(client.getOutputStream()), true); echoInput = new BufferedReader(new InputStreamReader(client.getInputStream())); while ((line = input.readLine()) != null) { echoOutput.println(line); System.out.println(echoInput.readLine()); } client.disconnect();
Quelquechose de faux?
Merci d'avance!
