First, I call JavaFX/OpenJFX JFX here.
I'm not an expert at JFX, I just read half of a book about JFX and be amazed by
it. Then I began to take some attention to JFX and be interested in it. JFX is
separated from JDK, well the news sound not so bad actually. The fact is JFX
isn't well-known, we sound little even noting about JFX in school and lots of
books which just teach awt/swing. Thus, the "bad" news at least can let some
guys notice what JFX is (*^_^*). And Here I can here only talk about the
future of JFX.
Why we use a technology? The answer is simple, just the technology is useful in
some application scenarios and better than the others.
What are JFX's application scenarios? It is written in
https://github.com/javafxports/openjdk-jfx, the mirror of the OpenJFX
repository:
OpenJFX is an open source, next-generation client application platform for
desktop, mobile and embedded systems based on JavaSE. ....BALABALABALA
So JFX's scenarios are desktop, mobile, and embedded systems, let us analyze
one-by-one.
1. Desktop:
competitors：QT，WebApp
advantages：Write once run everywhere(solve Why Linux haven't XXX?). Easy than
QT, build beautiful client quickly. Because of desktop's hardware higher and
higher. We can regard JFX'performance same as QT.
limitations：Well, nowadays WebApp are everywhere, a browser can solve almost
all of the problem, the desktop market is smaller and smaller, though client
app suite for some special scenarios, these scenarios are too small to feed
many programmers.
2. Mobile:
competitors：ReactNative, Flutter
limitations：Though ReactNative own many denounce, it also own huge developers
and full toolchain. Flutter is the other technology which bright me. With
beautiful UI and handy language Dart( similar to java ). It is perfect in my
eyes.
advantages：I haven't used JFX in mobile so I can't see what advantage JFX have.
If JFX can perform well like Flutter, well, JFX would have a good future in
Mobile.
3.Embedded systems:
competitors：QT
advantages：The embedded device is a big market, The car, all the screen in your
home in the future(Internet of things(IoT)), the public service devices like
the vending machine and other interactive devices, so embedded absolutely is a
huge enough market which can feed many JFX programmers. Compare with QT, same
as Desktop, JFX can quickly and easily write beautiful app although QT can
write the beautiful app too, it needs higher technological level and more time.
limitations：Performance, the inherent shortage(VM) let JFX can't run at some
performance sensitive scenarios like plant/workshop control system or
spacecraft control system ~~~///(^v^)\\\~~~，but with the development of science
and technology (hardware upgrade), lots of devices have higher performance, so
It is highly feasible by using JFX to build for-civil-use/home application. We
can't defeat QT in performance, but we can defeat it at applicability and just
don't get too far behind QT in performance. (bad example

What are you think about? Let's talk about it and draw a brilliant future for
JFX.
If this mail has no intention of offending someone, I hope you can forgive me.
Thank all those who contribute to JFX.
