## Class EchoTCPClient

- java.lang.Object
- - org.apache.commons.net.SocketClient
  - - org.apache.commons.net.discard.DiscardTCPClient
    - - 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.
