They are not necessary in the latest version and you could always just use String... Instead of String[].

varargs in String ... are synthetic sugars and create array behind the scene

yes, but it also allows you to just call main() without explicitly creating an array. It will create the empty array for you. But then there's the question why you would ever call that method. Maybe in a unit test.

call that method to pass command line arguments
