I am creating an application in JavaFX with an FXML file. The application will have a listview that takes in a person object class for firstName, lastName, and notes for personalHobbies. All with getters and setter. And a to string to with all the relevant items. Each class part is typed in a textField in the app by the user in the person list. And when a person is selected, all of the parts in the toString of each person class show like this: John Smith Hobbies include video games, playing, and writing.
The app also includes a button to add and delete a person from the list too. The problem is that all of the to string information shows up on the selection in the list, not just the first name by itself. I have been using an observable arraylist And everythibg but that works. This is my first post, and I am new to JavaFX so please forgive me, but I need help, thanks in advance.
