Writing in both C and Java, I might be a little more sensitive to
the differences between them.
Since C's main is supposed to have arguments (usually argc and argv)
but it is usual not to put them in if I am not using them, I prefer
the () form, with the (void) form when there are never any arguments.
That is unlike Java, where the argument signatures (I think that
is what they call them) must match.
To allow for varargs, most calling conventions used with C allow
for fewer arguments. As well as I know it, strictly that is only
allowed for actual varargs functions. Different calling conventions
could be used for varargs and non-varargs, but usually aren't.
I haven't looked yet how Java does System.out.format(),
though I use it more and more in my Java programs.
