Swing is still a good API for classic desktop applications.

​I did not invest a lot in Swing. As I understood it new applications should be written with JavaFX instead of with Swing. That is not the case?

I expect that JavaFX has more features as Swing. So it would not hurt to use it I would think.​

On Debian, either install the openjfx package (from the backports if you
are using Jessie) or install the Oracle JDK (you can convert the Linux
tarball into a .deb with the make-jpkg tool from java-package.

​Backport ​

​gives the same as main:
    libopenjfx-java libopenjfx-jni openjdk-8-jre openjdk-8-jre-headless openjfx

But my Java version is 7. Is something ​going wrong here?

JavaFX 8 requires Java 8. The earlier versions of JavaFX aren't as
mature, I wouldn't recommend them.

​But for Java 8 I need to install unstable packages I understood. Or am I mistaken?​

JavaFX isn't an official part of Java, but it's packaged with the JRE
distributed by Oracle. In Debian it's a separate package (openjfx).

​That explains it: the Debian distribution of Java is different as the Oracle one.
