JAVAFX:

• JavaFX is a set of graphics and media packages that enables developers to design, create, test, debug, and deploy rich client applications that operate consistently across diverse platforms.
• JavaFX is a software platform for creating and delivering desktop applications, as well as rich Internet applications (RIAs) that can run across a wide variety of devices. JavaFX is intended to replace Swing as the standard GUI library for Java SE, but both will be included for the foreseeable future. JavaFX has support for desktop computers and web browsers on Microsoft Windows, Linux, and macOS. JavaFX is no longer bundled with the latest Java.
• JavaFX Applications:

Written as a Java API, JavaFX application code can reference APIs from any Java library. For example, JavaFX applications can use Java API libraries to access native system capabilities and connect to server-based middleware applications.

How Do I Run a Sample Application?

The steps in this section explain how to download and run the sample applications that are available as a separate download with the Java Platform (JDK 7).

To download and run the sample applications:

1. Go to the Java SE Downloads page .

2. Scroll down to locate the JDK 7 and JavaFX Demos and Samples section.

3. Click the Demos and Samples Download button to go to the downloads page.

4. On the Java SE Development Kit 7 Downloads page, scroll down to the JavaFX Demos and Samples Downloads section.

5. Download the zip file for the correct operating system and extract the files.

   The javafx-samples-2.2.x directory is created and contains the files for the available samples. The NetBeans projects for the samples are in the javafx-samples-2.2.x\src directory.

A menu bar is a horizontal bar that acts as a container for menus. An instance of the MenuBar class represents a menu bar. You can create a MenuBar using its default constructor:

Menu is a popup menu that contains several menu items that are displayed when the user clicks a menu. The user can select a menu item after which the menu goes into a hidden state

Constructor of the MenuBar class are:

1. MenuBar(): creates a new empty menubar.
2. MenuBar(Menu… m): creates a new menubar with the given set of menu.
3. Using Menu Items:A MenuItem represents an actionable option. When it is clicked, the registered ActionEvent handlers are called.

Using a menu is a multistep process. The following sections describe the steps in detail. The following is the summary of steps:

• 1. Create a menu bar and add it to a container.
• 2. Create menus and add them to the menu bar.
• 3. Create menu items and add them to the menus.
• 4. Add ActionEvent handlers to the menu items to perform actions when they are clicked.
