!OpenJFX
Ubuntu 18.04だと，
 apt install openjfx
で必要なものをインストールして，
 export PATH_TO_FX=/usr/share/openjfx/lib
 javac --module-path $PATH_TO_FX --add-modules javafx.controls HelloFX.java
 java --module-path $PATH_TO_FX --add-modules javafx.controls HelloFX
とかして，コンパイルと実行ができた．
サンプルは https://github.com/openjfx/samples あたりを参考に．
