Want to learn, explore or use Java instantly without setup ?
Do you like Java but use python, groovy, kotlin or similar languages for scripts, experimentation and exploration ?
Ever wanted to just be able to run java from anywhere without any or very minimal setup ? Ever tried out Java 11+ support for running .java files directly in your shell but felt it was a bit too cumbersome ?
