print() methods.
One takes an argument. One doesn't. As long as the
argument lists can disambiguate the choice, this is allowed.
This is called overloading.
Also note, that the System.out.println() we've been using all along
is an overloaded method.
main(String[] args) is a non-overloaded method that has an
array of strings as arguments.
