Question 1

This is a name that identifies a component in the FXML file and will also become a variable name that you can use later in the Java code that you will write to run the application.
A) fx:id
B) fx_id
C) FXID
D) fx.URL

Accepted Answer

The attribute "fx:id" is specifically used to identify a component in the FXML file and can be used as a variable name in the Java code. The other options are not valid attributes or do not have the same purpose as "fx:id."

Question 2

This is a markup language that describes the components in a JavaFX scene graph.
A) SGML
B) HTML
C) XML
D) FXML

Accepted Answer

FXML is a markup language specifically designed for creating JavaFX user interfaces. It describes the components in a JavaFX scene graph in a hierarchical and structured way, allowing for easy manipulation and styling of the user interface. SGML and HTML are markup languages for general document formatting, while XML is a generic markup language that can be used for various purposes, including describing user interfaces. However, FXML is specifically tailored for JavaFX and provides additional benefits such as automatic bindings and event handling.

Question 3

The ________ is responsible for handling events that occur while the JavaFX application is running.
A) abstract class
B) main application class
C) controller class
D) super class

Accepted Answer

The controller class in JavaFX is responsible for handling events and user interactions that occur while the application is running.

Question 4

The Application class's ________ method is the main entry point for a JavaFx application.
A) start
B) init
C) addWindow
D) mainFX

Accepted Answer

The start method in the Application class is the main entry point for a JavaFx application. This is where the application's primary stage and scene are created and displayed. The init method is used for initialization tasks before the application is launched, addWindow is not a valid method in the Application class, and mainFX is not a valid method in JavaFx.

Question 5

In JavaFX, this component is commonly used as a GUI's root node.
A) List
B) AnchorPane
C) Button
D) ComboBox

Accepted Answer

AnchorPane is commonly used as the GUI's root node because it allows other nodes to be anchored to specific positions within the pane. This is useful for creating designs that are responsive to changes in screen size and layout.

Question 6

Oracle provides a free design tool named ________ that you can use to visually create a GUI.
A) EclipseLink
B) JavaFX
C) Scene Builder
D) Oracle ADF Essentials

Accepted Answer

Oracle provides Scene Builder as a free visual design tool for creating a GUI with JavaFX. EclipseLink is an open-source persistence framework, not a design tool. Oracle ADF Essentials is a framework for building enterprise-level applications, not a design tool specifically for building GUIs.

Question 7

A(n) ________ is a method that automatically executes when a specific event occurs.
A) flag register
B) action scheduler
C) callback routine
D) event listener

Accepted Answer

An event listener is a method that automatically executes when a specific event occurs. It "listens" for the event to occur and then triggers the associated method or function. The other options (flag register, action scheduler, callback routine) do not specifically refer to this concept of automatic execution based on an event occurring.

Question 8

This is a special annotation that must precede any nonpublic field declaration or nonpublic method definition that is used by the FXML file.
A) @FXML
B) finalFX
C) fx:id
D) #FXML

Accepted Answer

The @FXML annotation is used to mark nonpublic fields and methods that are used by the FXML file. This annotation is necessary for the FXMLLoader to inject values into the corresponding fields defined in the FXML file.

Question 9

This Scene Builder panel allows you to work with a component's properties, layout, and code.
A) Library Panel
B) Document Panel
C) Inspector Panel
D) Content Panel

Accepted Answer

The Inspector Panel is where you can view and modify a component's properties, layout, and code. The Library Panel contains a list of all available UI components that can be added to your project, the Document Panel displays a visual representation of your interface, and the Content Panel displays the content within a selected component.

Question 10

This is a component that can hold other components inside of it.
A) Container
B) Module
C) Node
D) Element

Accepted Answer

A container is a component that can hold other components inside of it, often used in graphical user interfaces or web development to organize and manage layout.

Question 11

Which of the following import statements is necessary to make the connection between the controller class and the application's FXML file?
A) import javafx.lang;
B) import javafx.scene.control;
C) import javafx.fxml;
D) import javafx.fxml.FXML;

Accepted Answer

The import statement import javafx.fxml.FXML; is necessary to make the connection between the controller class and the application's FXML file. The @FXML annotation is used to mark fields in the controller class that are bound to elements in the FXML file.

Question 12

Once you have created a GUI with Scene Builder, and saved it to an FXML file, you need to write a Java class that performs which of the following?
A) Loads the FXML file
B) Builds the scene graph in memory
C) Displays the GUI
D) All of the above

Accepted Answer

To create a fully functional GUI, all three options listed are needed. The Java class should load the FXML file, build the scene graph in memory and display the GUI to the user. Therefore, the correct answer is D - all of the above.

Question 13

Which of the following does not belong in a JavaFX scene graph?
A) Trunk node
B) Branch node
C) Leaf node
D) Root node

Accepted Answer

All the other options are valid types of nodes in a JavaFX scene graph. The trunk node is not a standard node type and does not belong in a scene graph.

Question 14

The Scene Builder ________ provides a list of JavaFX components that you can use in an application.
A) Inspector Panel
B) Menu Bar
C) Content Panel
D) Library Panel

Accepted Answer

The Library Panel in Scene Builder provides a list of JavaFX components that you can use in an application.

Question 15

To place a component in a GUI, you simply drag it from the Library Panel, and drop it into the:
A) Content Panel
B) Document Panel
C) Selection Bar
D) Inspector Panel

Accepted Answer

The Content Panel is where the components of a GUI are placed and arranged to create the interface. The other options listed are not appropriate for placing components. The Document Panel is where the overall document or project is displayed, the Selection Bar shows which component is currently selected, and the Inspector Panel provides information and options for the selected component.

Question 16

This is an action that takes place within a program, such as the clicking of a button.
A) Response
B) Input
C) Event
D) Incident

Accepted Answer

An event is an action that takes place within a program, typically initiated by the user. Examples of events include clicking a button, typing on a keyboard, or moving a mouse. Events can trigger responses within the program, such as displaying a message, updating a database, or opening a new window.

Question 20

A window in a GUI commonly consists of several ________ that present data to the user and/or allow interaction with the application.
A) modules
B) components
C) elements
D) buttons

Accepted Answer

Components are the best choice as they are the individual parts that make up a window in a GUI. Modules, elements, and buttons may also be present within these components, but do not fully encompass the various functionalities and visuals presented to the user within a GUI window.
