What does the controller class do JavaFX?

An FXML controller class can bind the GUI components declared in the FXML file together, making the controller object act as a mediator (design pattern). There are two ways to set a controller for an FXML file. The first way to set a controller is to specify it inside the FXML file.

What is the best practice for MVC in JavaFX?

Best Practice: Enforce Model-View-Controller (MVC) with FXML. JavaFX enables you to design with Model-View-Controller (MVC), through the use of FXML and Java. The “Model” consists of application-specific domain objects, the “View” consists of FXML, and the “Controller” is Java code that defines the GUI’s behavior for interacting with the user.
