[Epic]: Jupyter notebook functionality for Java

[ge0ffrey]

What happened?

This might be a very tall order and out-of-scope of this playground, but if the playground supports:

• [ ] surround it with docs (AsciiDoc or Markdown)
• [ ] support multiple snippets in one page on which one continue after the other
• [ ] import from Maven Central

it becomes as powerful Java alternative to Python's Jupyter notebook or Kotlin's notebook, making it much easier to teach the Java language to new students.

To be honest, I (personally) think this is way too much for the playground (also it's supposed to be very restricted, e.g. you can't access files, network or similar) so many this probably won't work on it.

For things like that, it might be better to just use a Java kernel for Jupyter notebooks, e.g. https://github.com/SpencerPark/IJava (which seems to be based on jshell as well). Using something like that allows to use IO etc.

Also, JavaFX Notebook might be relevant for that use-case.
