In this youtube Video I describe how to write a platform independent Java Swing application with FlatLaf look and Feel. In less than a quarter of an hour I am writing a small application with a Textarea to edit content and a Write and a read Button to write and read the File and also an exit button. One Correction: not a Web but a Desktop application. Web comes later. Dunno why but it was really late!!!

Very nice! Just watched the video and while that’s all new to me, it makes sense and is familiar! Do you prefer NetBeans over IntelliJ IDEA? ---

Netbeans contains the UI Designer. IntelliJ can have an UI Designer when installing JFormDesigner, it’s a plugin which costs 30 per year. Netbeans is completely for free. I am using both IDE’s. I prefere Netbeans for Desktop-Projects with Java Swing. Definitely, while the Drag and Drop UI Designer is really nice. Why I am preferring Swing for the UI? While the jar File can run without any changes on Windows, MacOS and Linux. On all platforms runnable with java -jar nameoftejar.jar That makes it for me simple to test the app on all platforms before I am starting to build my jPackage for the platforms and deploy the Software to Customers. Internally we even use jars directly as program files while we even are too lacy to build Packages. And while it works without any problem. ---

So far I installed JDK and NetBeans. Then downloaded your GitHub Project. JDK `https://www.oracle.com/java/technologies/downloads/` NetBeans `https://netbeans.apache.org/front/main/` When I opened the project it seemed to have less items in the project. And when I run it I get: `Exception in thread "main" java.lang.RuntimeException: Uncompilable code - exception javax.swing.UnsupportedLookAndFeelException is never thrown in body of corresponding try statement at swingexample.SwingExample.main(SwingExample.java:1)` Should I be able to download the project and just hit run? Thanks for your patience! 🙂 ---

download the flatlaf from [formdev.com](http://formdev.com) and then import it like I sowed in the video while I was not delivering it with. I was not placing it as file in project but as link lao. setup in your project properties the right java version. ---

When you add a jar, do you have to give permissions in Mac OS? Every time I add the jar, it doesn’t actually add it. I downloaded from: “[https://repo1.maven.org/maven2/com/formdev/flatlaf/3.5.2/flatlaf-3.5.2.jar](https://repo1.maven.org/maven2/com/formdev/flatlaf/3.5.2/flatlaf-3.5.2.jar)” ---

depends on our permissions of your computer if you have write permissions it will work without any problem. I was adding it without the need of giving permissions and tested on McOs, Windows and Linux just done it again on my Office Mac ![grafik](https://ifnotnil.com/uploads/default/original/2X/a/a80f9e088dd31713684aac44ad1218a62cf1666b.png) and it was dded without any problem, project was running after setting the Java Platform in project Settings ---

> [@thorstenstueker](#): > > depends on our permissions of your computer Thanks! That did the trick. I made a folder, but everything in it and applied the folder permissions down. Interesting that I don’t usually have to do that. It now runs! 🙂 ---
