## org.apache.commons.net.echo
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.

See Also:
  `EchoUDPClient`, `DiscardTCPClient`

Field Summary
`static int` | `DEFAULT_PORT` The default echo port.

Fields inherited from class org.apache.commons.net.SocketClient

Constructor Summary
`EchoTCPClient()` The default EchoTCPClient constructor.

Method Summary
`InputStream` | `getInputStream()` Returns an InputStream from which you may read echoed data from the server.
