I've tried every way of typing the link to the fxml file. I've looked online but haven't seen this exact issue. It was originally the generic "name".java file before I tried to figure out the bug, and even the normal file wasn't working.

You are throwing an exception in the initialize method of the controller that's why you get it

Just delete the line containing throw new UnsupportedOperationException(...); from initialize() to make that method empty. That code is generated by NetBeans, and you don't want it. Possible duplicate of FXML Initialize() throws InvocationTargetException.

You are throwing an exception in the initialize method of the controller that's why you get it

I'm sorry, I'm still so new at GUI's. Where exactly is the exception and how do I fix it?

– Simca Wood
Nov 23 '18 at 22:03

Just delete the line containing throw new UnsupportedOperationException(...); from initialize() to make that method empty. That code is generated by NetBeans, and you don't want it. Possible duplicate of FXML Initialize() throws InvocationTargetException.
