The single thing I would say Java is missing, from the perspective of a beginner, is the ability to change code while running it. Eval and Exec are useful functions, and there is no way to replicate them in Java.

Lists in Java are an unholy pain that redefine cruelty in an entirely new way. You can't make a list, to the best of my knowledge, that accepts arbitrary inputs. Does the utter lack of a slice operator count for the addition of multiple lines of code to replace what is normally three or four characters?

Please, tell me how. This is an honest question. I have been learning Java since school started, and I miss my functional techniques.
