In the past I wrote two posts about Java sripts and their portability using shebang. As far as I can tell everything in these two installments is still valid, only now, in Java 21, thanks to JEP-445 things can be even simpler. In this post I’ll try to describe fist the changes introduced by this JEP, then go deeper on how they relate to the “scripts in Java”. I’m going to cover how you can simplify your main method, get rid of the class surrounding it, and even show you when it won’t work.
shebangin a way which makes it portable?
