You're very close. What you need to remember is when you're calling a method from another class you need to tell the compiler where to find that method.

So, instead of simply calling addWord("someWord"), you will need to initialise an instance of the WordList class (e.g. WordList list = new WordList();), and then call the method using that (i.e. list.addWord("someWord");.

However, your code at the moment will still throw an error there, because that would be trying to call a non-static method from a static one. So, you could either make addWord() static, or change the methods in the Words class so that they're not static.

My bad with the above paragraph - however you might want to reconsider ProcessInput() being a static method - does it really need to be?
