Explain the sequence of method calls that are needed to run a JavaFX GUI application.
What will be an ideal response?
A JavaFX GUI application is assembled and displayed in a start method. Most GUI applications override
the start method that is inherited from the Application class. The start method creates the components and adds
them to a layout container, which is then added to a Scene object by way of its constructor. The Scene object is then added
to a Stage object by the Stage object’s setScene method.. The Stage object, which represents the GUI application,
becomes visible to a user by way of its show method.
