Using ellipsis in main method?

Question

If i use ellipsis in main method would it make any difference?

public static void main(String... args) {

}

Answer 1

No difference. That "ellipsis" syntax is called varargs, whose parameter type is actually an array.

This means there are actually three possible signatures of a valid main() method:

public static void main(String[] args) {}
public static void main(String... args) {}
public static void main(String args[]) {}

Answer 2

It does not make any difference, since the JVM turns the ellipsis (also called "varargs") into an array at "compile" time:

void myMethod(final X... args)

is exactly the same as

void myMethod(final X[] args)

or (less frequent)

void myMethod(final X args[])
