Class EchoTCPClient

java.lang.Object
  extended by org.apache.commons.net.SocketClient

          extended by org.apache.commons.net.echo.EchoTCPClient

public final class EchoTCPClient
extends DiscardTCPClient

The EchoTCPClient class is a TCP implementation of a client for the Echo protocol described in RFC 862. To use the class, merely establish a connection with connect and call getOutputStream() to retrieve the echo output stream and getInputStream() to get the echo input stream. Don't close either stream when you're done using them. Rather, call disconnect to clean up properly.
