JavaFX Tutorial: Kotlin vs Java, which is Better for JavaFX?

Recently, I have been experimenting with the combination of JavaFX and Kotlin. As Kotlin also runs on the Java Virtual Machine (JVM) and is a very close sister of Java, the switch is straightforward. In this video, I show you the difference in code style.

You can also find the description on my blog:

And here are the sources of the project used in this tutorial:

You can achieve the same thing in Java using builders, except that builders allow you to create immutable objects via the ctors, while this approach in Kotlin creates a mutable object and calls setters afterwards - not ideal

Nesting code blocks endlessly is certainly not readable. Just write code line by line like Java. Compared to Kotlin, Java code is much more readable and becomes easy to reason about when the application grows

In my opinion, the Java version that is more readable and easy to understand.
The best way to create UIs is using the declarative DSL instead of the imperative java/kotlin code.

Is there any exemple out there with groovy?
