Linking RadioButton to class

[Klaas Vredevort]

Hey guys

Listen I need some help. I have two classes, one an applet with RadioButtons in a panel. The other is a File Reader. It is a Hangman game with four files containing words. The user chooses a category from which the random word is called.

I want to link the RadioButton to the category. I will paste the code (both classes) entirely and then tell you at which line the category is called, as well as the RadioButtons.

The Buttons can be found in init()

and I think the categories are quite straightforward. It asks for inputCategoryChoice and then it takes that to read the file. The files are called 1.txt, 2.txt etc
