What is examples.telnet.WeatherTelnet.java?

✍: FYIcenter.com


examples.telnet.WeatherTelnet.java is an example program of a trivial use of the TelnetClient class.

examples.telnet.WeatherTelnet.java connects to the weather server at the University of Michigan, um-weather.sprl.umich.edu port 3000, and allows the user to interact with the server via standard input.

You could use this example to connect to any telnet server, but it is obviously not general purpose because it reads from standard input a line at a time, making it inconvenient for use with a remote interactive shell.

The TelnetClient class used by itself is mostly intended for automating access to telnet resources rather than interactive use.
