With
Java 13 in use and the early releases of 14 and 15 ostensibly available to work with (I didn't try to download them so I'm not sure where they stand as far as usefulness), should I continue to learn Java 8?
Is it still in popular use outside of maintaining legacy programs?
Is it a waste of time to learn 8 and begin building things with it?
My goal is to get a job in Java development and I have an older book I am working from (bought in 2015/2016)
