At least until the Linux developers remove it... My understanding is
that sysfs is currently "deprecated", the replacement being libgpiod -- a
"character" device driver.
Unfortunately, for libgpiod, JAVA probably needs an interface library
to be created -- quick search finds
https://github.com/mattjlewis/diozero (though there are some mentions of
sysfs in the commentary, but perusing
https://github.com/mattjlewis/diozero/blob/main/system-utils-native/src/main/c/com_diozero_internal_provider_builtin_gpio_NativeGpioDevice.c
appears to be the libgpiod chip devices).
There is also this one https://github.com/sgjava/java-periphery
