Thanks for the kind and useful reply. I recall from the immemorial (a long time ago i.e. mid 80’s) that LISP was the putative programming language for AI development and I was under the impression that one could segue from Java to LISP or more recent languages (i.e. Python as you asserted). I retired very early (in 2005) and since the advent of COVID, I started to dust my Java skills and write code again (so much has changed, a steep learning curve I must admit, modules, lambda, JavaFX, etc.) I was not even aware that Java had an AI framework, something to dip my nose into and I will check Python as well.
