JavaFX applications are based on JavaFX's Application class. Perhaps you are unfamiliar with this class and have questions about using Application and on what this class offers your application code. This post attempts to answer these questions while exploring Application.
Introducing Application
The javafx.application.Application class provides a framework for managing a JavaFX application. This application must include a class that extends Application, overriding various methods that the JavaFX runtime calls to execute application-specific code.
An application can call Application methods to obtain startup parameters, access host services, arrange to launch itself as a standalone application, interact with the preloader (a small application that's started before the main application to customize the startup experience), and access the user agent (Web browser) style sheet.
