For the second video in this "JFX In Action" series, I talked to Daniel Zimmermann. He got my attention when he recently tweeted: "To your dismay I have to tell you I write all my desktop applications using Kotlin and JavaFX". Why is he a big Kotlin AND JavaFX fan? I asked him and got a demo of the network test application that he is working on.

About Daniel Zimmermann

In the video, he also shows two other JavaFX applications he (co-)worked on: Kloster Disentis and Leviat.

You can find Daniel on Twitter and Mastodon.
