refactor: refactor java parser (#1771)

[XDRAGON2002]

Closes #1771

[terriko]

Caused a merge conflict with the java parser refactoring. I've attempted to resolve via the web interface but if black fails you may need to take a look at it @XDRAGON2002 .

Looks like I managed to resolve the merge conflict without breaking linting. I'm going to go ahead and merge this now. It may go and cause conflicts in the others.
