I am trying to create a quiz. The quiz starts by reading a file. The file has 6 questions. Each question gets its own card in the cardlayout. Each card has a button to the next CardLayout. Questions 1 - 5 should have a 'next' button that links to the next card. Question 6 should have a button that says 'get results' this will link to a card that displays one of the possible results cards. (these are still in progress, for now I am simply trying to get the button created and am testing it with the .previous() method). As of now each card has a next button and it seems the statement that adds a 'get results' button isn't being reached. take a look.

I've tried making the bottomPanel its own method that returned a bottomPanel. this did not achieve the desired results because it was called in the constructor and I don't think the currentCard variable was adding up every time. Right now this code reads all the questions fine and all the answers fine. But it creates a next button on every single card instead of on the first 5 only. if there's a variable in a weird place or a suspicious print call it's most likely leftover code from a previous test that I forgot to delete/comment out.
