 /***
 30  
  * This is an example program demonstrating how to use the EchoTCPClient
 31  
  * and EchoUDPClient classes.  This program connects to the default echo
 32  
  * service port of a specified server, then reads lines from standard
 33  
  * input, writing them to the echo server, and then printing the echo.
 34  
  * The default is to use the TCP port.  Use the -udp flag to use the UDP
 35  
  * port.
 36  
  * <p>
 37  
  * Usage: echo [-udp] <hostname>
