Solution 1:[1]

Most likely, you copied the options from somewhere, but you didn't copy an ASCII dash, but some other unicode dash, that looks very much or even exactly the same as an ASCII dash in your font. Like the em-dash. (\u2014)

With ASCII dash:

java -version
java version "17" 2021-09-14 LTS [...]

With em-dash (\u2014): (you can copy-paste java —version to try)

java —version
Error: Could not find or load main class —version

Solution: delete the dashes, and type an ASCII dash on your keyboard instead.
