The NewFXMain.java code contains a list of API imports.   I notice that the public class NewFXMain extends Application.  So would I be correct in saying that this uses the import javafx.application.Application as a template and then modifies its behaviour or adding additional functionality.

    In this case, Application is an abstract super class.  It contains one abstract method, start, which must be implemented by the JavaFX main class.  start is like the main method for JavaFX applications.  In fact, this inheritance structure is so crucial to JavaFX projects, NetBeans automatically creates it when you start a new JavaFX project.

    If you're curious, NetBeans offers a shortcut to inspect any particular class, like Application. Hold ctrl and click Application.
