Java Swing vs Java FX

Difference Between Java Swing vs Java FX

When it comes to the Java ecosystem, Swing act as a toolkit for the GUI widget. Swing is responsible for providing the APIs for creating the user interface for Java programs. Before the advent of Swing, AWT, i.e. Abstract Window Toolkit, was responsible for providing an advanced form of user interface components. But Swing supersedes the AWT library and comes up with a look and feel that resembles most of the platform. These created UI components are not only advance in terms of appearance and feel, but they are also pluggable in nature. That means the underlying platform is not bounded with a specific set of UI components. UI components like buttons, labels, and checkbox can be easily created with Swing APIs. Thus, Swing is more flexible in nature than AWT.

Swing provides a designer with a regular UI component but advanced components like tabbed panel, scroll panes, tables, trees, etc. Swings have some added advantage over AWT, which makes Swing overtake AWT in developing UI components. UI components in Swing are developed entirely in Java and thus, they are platform-independent, which is unlike AWT components. Swing’s framework is MVC, i.e. Model-view-controller, which provides an abstraction between the graphics UI and the underlying code structure. This abstraction helps the UI component writer in maintaining “separation of concern” like architecture. Any developer can have access to all available Swing classes with their complete documentation in the Java API guide. Swing’s classy aspect is its modular-based architecture because this writer can come up with their own custom UI implementation of standard UI components, resulting in overriding the default implementation using the Java inheritance concept.

JavaFX act as a standard GUI library, having extensive support for desktop computer and different web browsers on a different operating system like Windows, Linux etc. Desktop applications can be created efficiently using JavaFX, which act as a software platform. In the earlier edition of JavaFX, scripts were being used to build JavaFX applications; these scripts were declarative and static in nature. But with the advent of the JavaFX 2.0 version, it is implemented as a Java library, which means applications now can be written using native Java code instead of scripts. With JavaFX, Java developers can address all the issues which come along with modern UI design. A complex set of controls are required in the modern UI, the responsiveness of UI is highly dependent upon concurrency, but Java multi-threaded code requires a lot of boilerplate code addition.

All these challenges can be successfully meet with JavaFX; Sun’s strategy for providing Rich Internet Application makes the life of Java developer easier, which is in line with Adobe’s Flex and Microsoft’s Silver light tool. Flex and Silver light tool utilizes XML, a declarative language, whereas JavaFX uses their own version of scripts. All Java developers who are well known with Swing APIs can easily confront JavaFX scripts and re-write their UI components, which are more versatile and internet-rich. These JavaFX scripts not just include new APIs but also has access to all Java packages. A scene is created as a hierarchy of visual nodes and can be created with scene API, resulting graph scene can efficiently respond to the user interaction. The level of abstraction provided with APIs is efficient, and it provides all kind of automatic optimization. Any ordinary Java application can also utilize scene graph APIs. JavaFX 8 has introduced some of the new features like 3D graphics support, rich text support, sensor support etc.

Below is the top 6 difference between Java Swing and Java FX:

Key Differences Between Java Swing and Java FX

Both Java Swing vs Java FX performance is recommended options in the business. Let us examine some of the key difference between Java Swing and Java FX:

1. Swing is the standard toolkit for Java developer in creating GUI, whereas JavaFX provides platform support for creating desktop applications.
2. Swing has a more sophisticated set of GUI components, whereas JavaFX has a decent number of UI components available but lesser than what Swing provides.
3. Swing is a legacy library that fully features and provide pluggable UI components, whereas JavaFX has UI components that are still evolving with a more advanced look and feel.
4. Swing can provide UI components with a decent look and feel, whereas JavaFX can provide rich internet application having a modern UI.
5. Swing related classes can be found in the Java API guide with complete documentation, whereas JavaFX doc is available in various format with comprehensive detailing and file support.
6. Swing, since its advent, can create UI component using standard Java component classes, whereas Java FX initially uses a declarative language called JavaFX Script.
7. Swing has a UI component library and act as a legacy, whereas JavaFX has several components built over Swing.
8. Swing has support for MVC, but it is not consistent across a component, whereas JavaFX support is very friendly with MVC.
9. Swing has various IDEs, which offer a tool for rapid development, whereas JavaFX has also support from various IDEs as well, but it is not as mature as Swing.
10. A swing was renamed from Java Foundation Classes, and sun microsystems announced it in the year 1997, whereas JavaFX was initially released in December 2008 by Sun microsystem and now acquired by Oracle.

Java Swing and Java FX Comparison Table

Let’s look at the top Comparison between Java Swing and Java FX.

Conclusion

Both are utilized heavily in the Java ecosystem for building UI components. These UI components are based on MVC pattern and pluggable in nature. Another aspect is that they are independent of the underlying platform; developers need to be aware of the Java concepts and can create UI components. Swing has an impressive number of UI components available, which has built-in classes for every UI need, i.e. button, panel, frame etc. On the other hand, Java FX has UI components that are originally based on Swing since Swing arrived much earlier than JavaFX.

JavaFX can provide the software platform, for writing rich internet application which has modern UI, with a sophisticated look and feel. It is still evolving and expected to grow in the future. From a Java developer perspective, both technologies are highly useful in writing pluggable UI components. With its vast UI component library, Swing can provide added advantage to the developer, whereas when it comes to design modern and rich internet application, JavaFX can supersede Swing.
