Board is certainly not a class that comes with your JSE distribution. I suggest you'd read that example again, maybe it's one of their classes and they have shown the source of that class.

kind regards,

The easy way to turn off automatic updates for Windows 10/11

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
