There's several layers to this question: 1) This sounds ignorant to ask at this point, but how in the heck does one use the console interface in IntelliJ? That would seem useful here. (As opposed to CodeGym where it's just "there".) 2) Since I can't play with any file names on the console interface, it makes it difficult for me to check my work. Any insights wiser minds than my own can contribute here would be greatly appreciated! : )
