JavaFX is a framework for building rich, cross-platform graphical user interfaces in Java. It provides a set of graphics and media packages that allow developers to create modern and responsive user interfaces with rich multimedia and animation capabilities. Here's a tutorial to get you started with JavaFX:
Install JavaFX: JavaFX is included with Java Development Kit (JDK) 8 and later versions. If you don't have JDK 8 or later installed on your system, download and install it from the Oracle website.
Create a new JavaFX project: To create a new JavaFX project in your favorite IDE, select "New Project" and choose "JavaFX" as the project type. If your IDE doesn't have a JavaFX template, you can create a new Java project and add the JavaFX libraries to the classpath.
Build the user interface: JavaFX provides a set of UI controls such as buttons, labels, text fields, and more. You can drag and drop these controls from the palette onto the scene builder to create your UI. You can also use FXML to define your UI declaratively.
Add event handlers: JavaFX provides an event-driven programming model, where you can attach event handlers to UI controls to respond to user input. You can use lambda expressions or inner classes to define event handlers.
Add multimedia and animation: JavaFX provides rich support for multimedia and animation, such as playing audio and video files, creating animations, and using 3D graphics. You can use the media and animation packages to add these features to your application.
Test and debug your application: You can run your JavaFX application by right-clicking on the main class and selecting "Run As" > "Java Application". You can use the debugging tools of your IDE to debug your application.
Package and deploy your application: Once you've tested and debugged your application, you can package it into a JAR file or a native executable using tools such as Maven, Gradle, or Ant. You can also deploy your application to the web or desktop using technologies such as Java Web Start or JavaFX Packager.
JavaFX provides a powerful and flexible platform for building modern and responsive user interfaces in Java. With the above steps, you should be able to start building your own JavaFX applications.
