I am building a JavaFX GUI and have 2 scenes/windows.

One as the main GUI and a second that shows up when adding a booking.

The booking FXML window uses BookingWindowController.Java which contains the form code and stores the information in an array list like seen below

ArrayList<Surgeon> surgeonList;

The surgeon class has getter and setter methods as the data fields are private.

I can access this data from the same controller file using

String x = surgeonList.get(0).getSpeciality();

but this code does not work when trying to access it from my main window controller file (MainPortalController.java) which needs to be able to access the data as it contains my display text area.

Maybe instead of an ArrayList u should use an ObserveableList. Did you think about using a view model and share it between both controllers? – kayf Apr 15 '21 at 04:42
A much better solution u can find here https://stackoverflow.com/questions/14187963/passing-parameters-javafx-fxml from @jewelsea – kayf Apr 15 '21 at 04:47
It's for a school project and we have to use array lists. – Nighthawk Apr 15 '21 at 06:30
An `ObservableList` is an `ArrayList`... – James_D Apr 15 '21 at 10:27
