About the second file you sent

What it is

A single Java file, but every one of its 314 lines is commented out — nothing in it would run or compile as-is.

What's inside

A scrapbook of snippets in several languages: Python battery/multiprocessing examples, Java-calls-Python approaches (GraalPython, ProcessBuilder, Jython), plain HTML pages, and JavaScript DOM code.

Also in there

Some handwritten maths jottings with trig and log terms, and a leftover 'Hello World' template from an online compiler.

If you want it running
