TCP Daytime implementation using Java

DaytimeServer.java

package net.tcp.daytime; import java.io.IOException; import java.io.OutputStreamWriter; import java.net.ServerSocket; import java.net.Socket; import java.util.Date; public class DaytimeServer { public final static int DEFAULT_PORT = 13; public static void main(String[] args) { int port = 1001; try { ServerSocket server = new ServerSocket(port); Socket connection = null; while (true) { try { connection = server.accept(); OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream()); Date now = new Date(); out.write(now.toString() + "\r\n"); out.flush(); connection.close(); } catch (IOException e) { e.printStackTrace(); } finally { try { if (connection != null) connection.close(); } catch (IOException e) { } } } } catch (IOException e) { System.err.println(e); } } }

DaytimeClient.java

package net.tcp.daytime; import java.io.IOException; import java.io.InputStream; import java.net.InetAddress; import java.net.Socket; import java.net.UnknownHostException; public class DaytimeClient { public static void main(String[] args) { String hostname = null; if (args.length > 0) { hostname = args[0]; } else { hostname = "localhost"; } try { InetAddress theAddress = InetAddress.getByName(hostname); Socket theSocket = new Socket(theAddress, 1001); InputStream timeStream = theSocket.getInputStream(); StringBuffer time = new StringBuffer(); int c; while ((c = timeStream.read()) != -1) time.append((char) c); String timeString = time.toString().trim(); System.out.println("It is " + timeString + " at " + hostname); } catch (UnknownHostException e) { System.err.println(e); } catch (IOException e) { System.err.println(e); } } }
