Obviously we need to keep those, but they don't need to be declared as `public static void main(String[])` which is misleading. So instead we rename these methods to `meth()`, and also we remove the `String[]` parameter when it's not needed by the test.

Verified that the test failures are unrelated, will help you sponsor
