Hi, I've decided to make a hangman game. I made this in Python last year, however I'm a little bit stick in Java, since I'm quite new to as well as Swing.
Anyway, the problem I'm having is that my while loop keeps terminating if I enter 1 incorrect letter, but it is fine if I keep entering the letters which are in the chosen word.
I think i've made drawing the line a bit too complicated but it's seem to be working fine.
