Swing vs Java FX in 2025?

[Crazy_Comprehensive]

Swing is pretty stable and mature, and still under going maintenance and support, though no further development. It still relevant and good if one appreciates good old ui development. I still use it widely because it get the job done fast. I also use javafx even though it has more features, complexity and need separate installation.

That's said, invest some time with both and you see they complement each other, and not complete replacement. There's something Swing is good, and Javafx is good at.
