Treehouse TeacherI think you want to call validate
and not validateGuess
(which I actually don't see here).
It seems that validateGuess
is returning a boolean, but you are attempting to store that in letter, which is a char
. That is what the type conversion error is talking about.
(I wrapped your code in 3 backticks followed by java so I could get the pretty color coding)
Let me know if that fixes it, I think it will!
