For the project I'm doing, I need to be able to guess letters. The fact that it is not letting me use "guess" is very problematic. What is the problem and how do I fix it?

How are you calling the guess function? Since it's a part of your HiddenKeyword class you need to

//Create an instance of HiddenKeyword
HiddenKeyword hk = new HiddenKeyword();
hk.guess(charToGuess);

My suggestion is you get rid of all of the miniature classes. All these methods are functionality of a simple Hangman class, splitting it up this much will just cause confusion and make situations like this to debug.

How would I go about about getting rid of the "miniature classes"? Sorry, I'm very new to programming and don't have the slightest clue as to what I'm doing.

Something like this

public class Hangman()
{
    public static void main(String[] args)
    { 
        Hangman hangman = new Hangman();
        hangman.play(); // You already have this set up
    }

    //play method
    //guess method
    //printstate method
    //gameover method
    //etc
}

Just put all the methods in the scope of one class
