This seems to be a pretty straight forward and easy project. The guidelines provided are easy to follow and it should be no trouble at all to write it up in 14 hours as asked. I have around four years of experience writing Java software, with a few small applications already posted onto GitHub.
As I said, the guidelines for the program itself are already laid out, and it should be simple to generate the needed code. I do, however need the getRangedInput and the getYNConfirm methods in order to properly implement them as given. I could write up my own, but I'm assuming there's a certain version you are expected to use.
Besides that, everything looks easily doable. Feel free to get in contact with me so we can flesh out details.
