I'm not 100% sure, but I've seen people have this error before using this System.console() in their own IDE. I think the best solution is to do these exercises in the Treehouse workspace where this console is built into the environment.

Outside of Treehouse, there is more than one way of receiving input from the command line. I prefer the Scanner class.
