Java GUI Frameworks Guide
Once you’ve graduated from creating simple console based applications, programs which graphical user interfaces (or GUI) are the next step. Java has several GUI libraries or “frameworks” which provide support for creating modern and feature rich user interfaces.
Bear in mind that there are actually almost 10 different (including variants) GUI frameworks in Java. However, we will only be discussing the three most important and well known frameworks in this article. The name of these three frameworks are listed below:
The goal of this article is to do a basic review on these three and explain which one of them is the best choice for someone looking to begin GUI development in Java. We’ll be starting with the oldest (AWT) and end with the newest (JavaFX).
AWT
AWT or Abstract Window Toolkit provides interface for Java Programmers to create GUI’s. It’s the oldest Java GUI framework, and thus also the most mature, documented having been tested and tried thoroughly.
AWT has sort of become a legacy framework by now and it’s use is negligible compared to other GUI libraries like Swing and JavaFX. It’s is rather outdated and lacking in advanced components that modern GUI’s of today require. If you wish to create a rich user interface, AWT is not the best option. However, it’s still a suitable choice for smaller and simple GUI interfaces.
AWT has a pretty strong legacy, as the Swing framework is actually based off AWT. There is also the SWT GUI framework which has strong roots in AWT. For these reasons, it’s relatively easy for an AWT user to switch over to Swing. Despite all this though, AWT is a GUI framework better left as a legacy.
Bonus fact: Sometimes (rarely) while working with Swing or JavaFX you will find yourself having to import classes from AWT. To me, It just shows how deep AWT’s roots run.
Swing
Swing, the successor to AWT which builds directly onto it, fixing and replacing many of it’s features with better ones or simply adding extra functionality onto existing ones (like tool-tips, borders and icons). The components in Swing are also less resource intensive compare to AWT.
Despite all this though, Swing is quickly becoming a legacy GUI library with it’s use mainly being restricted to old projects which need to be maintained. It would be rare to see a new GUI project nowadays using Swing. The reason for this is the introduction of a newer GUI framework, JavaFX which is meant to replace it.
Swing was a very popular library in it’s prime as it was the best GUI framework (for most) option available. Even now in 2020 it likely still holds a significant portion of the total GUI developers in Java. (mainly in projects that were built using swing in the past). The reason being that it’s hard to make that transition from one framework to the other, especially on a large scale such as a company.
SWT
There is an alternative version of Swing called SWT, (Standard Widget Toolkit) created by the IBM group. It was designed for the purpose of creating a more native feel to the GUI and most importantly, creating a GUI framework that runs well (faster) on the Eclipse IDE. Of course, it has its own downsides too (when compared to Swing) such as requiring native DLLs across different systems. It’s not really used nowadays, neither is it very recommended.
JavaFX
JavaFX is the latest Flagship of Java/Oracle replacing Swing, promising to be the new standard in creating rich desktop and web applications. Majority of the new Java GUI programs being developed in the last decade have been using JavaFX.
Since it’s one of the newer GUI Libraries introduced in Java, it understandably produces a more modern and rich look to its GUI’s than the older Swing and AWT.
One of it’s major selling points is it’s support for Mobile apps. Any JavaFX program you write on desktop/windows will also run on Android and iOS. Another plus point is how JavaFX handles separation between the CSS, FXML and Controller code, making it nice and simple.
If the above reasons weren’t enough to convince you, JavaFX also has a design tool called the “Scene Builder”. It’s basically a drag and drop system where you select components and “drop” them onto the window. Personally I’m not a very big fan of such a thing, (I prefer the traditional way) but I know that alot of people appreciate and use the Scene Builder.
An older library like Swing has the advantage of being older and has had time to fully mature and develop as a GUI framework. However, JavaFX is still receiving updates and improvements so it’s expected that it will catch up soon. In a way it’s actually a good thing that JavaFX is still “evolving” compared to Swing which is no longer being developed.

Conclusion:
If you in 2020 (or later) want to learn one of the above Java GUI Frameworks, I highly recommend you go with JavaFX. Swing is still a good GUI framework, but it’s being left behind (due to newer advancements). JavaFX on the other hand likely has a long life span ahead of it before it gets replaced by anything.
Your choice doesn’t have to complete binary either. Due to the way they are built, you can actually use a hybrid of Swing, AWT and JavaFX components in a single GUI. It’s especially useful for people who will be converting a pre-existing Swing or AWT GUI to the newer JavaFX, allowing for a smooth transition.
Hopefully this article was an informative read. There wasn’t much to decide here really (with regards to the best Java GUI Framework) since the choice was fairly one sided, but hopefully you found this little “history lesson” interesting.

Best Java GUI Frameworks
Java is a great programming language to create full applications. It provides both backend as well as frontend capabilities to developers. Various GUI (Graphical User Interface) frameworks are available today for creating Java applications in a faster and more efficient way.
The best Java GUI frameworks widely used by Java Developer Community for creating rich GUI based Java applications are

JavaFX
The latest flagship of Oracle is JavaFX and is counted at top among the Best Java GUI frameworks. JavaFX is the latest toolkit of Java/Oracle replacing Swing to create rich desktop as well as web applications. Many new Java GUI programs are being developed using JavaFX.
It produces a modern and rich look to its GUI’s when compared to the older Swing and AWT. It is also supported for Mobile apps. Any JavaFX program you write on desktop applications will also work fine on Android and iOS. JavaFX is nice and simple to use.
AWT
The Abstract Window Toolkit (AWT) can be called as very foundation of swing. AWT has optimized performance but still lacks some advanced features.
It is perfect for smaller a Java UI application that doesn’t require various rich user interfaces. This is being used for many years and has proven to be good for Full stack Java developers.
AWT supports Graphical User Interface programming. Some important features of AWT are:
- Native user interface components.
- Graphics and imaging tools for example shape, font classes.
- A robust event-handling model.
- Data transfer classes for easy cut-paste actions
Apache Pivot
Apache Pivot is an open-source framework platform for building intensive applications in Java or any JVM-compatible language. It has been released under the Apache License version 2.0.Its main aim is to develop rich internet applications that can also be applied to desktop applications.
It has been developed by Apache. Apache Pivot allows developers to easily construct great cross-platform and well-connected beautiful applications in Java/JVM language (JavaScript, Groovy, or Scala). It provides enhanced productivity and usability features of a UI toolkit.
Swing and SwingX
Swing is the primer framework of choice for building new GUI-based Java applications. Swing has a lot of rich UI components. Swing is the successor to AWT as it fixes and replaces many of its features with enhancing them by adding extra functionality. AWT has more comprehensive components than Swing
SwingX is based on the features of Swing and its main role is to create rich components for swing. It comprises some niche components; one such is such as TreeTable which can do sorting, filtering and searching. It also supports searching with a highlighting option.
SWT
SWT (Standard Widget Toolkit) was created by IBM for Eclipse IDE and is one of the Best Java GUI Frameworks. SWT uses the platform’s native widgets with the help of JNI. It is not related to Swing and AWT at all. It is said to be the alternate version of Swing.
SWT is created by IBM with the main purpose to create a native GUI. It is fast and can be run on the Eclipse IDE. When compared to Swing, it still requires native DLLs across different systems in use. Its users are decreasing day by day as more comprehensive Java GUI tools emerge in the market.
