Arrays as parameters

Problem

Varargs method invocation

You are given a method with the following declaration:

public static int method(int[] array, int... vararg) { return 1; }

Select all correct ways to invoke this method.

[x] method(new int[] { 1, 2, 3 }, new int[] { 4, 5, 6 });
[ ] method(1, 2, 3);
[x] method(new int[] { 1, 2, 3 });
[x] method(new int[] { 1, 2, 3 }, 4, 5);
[ ] method();

Correct.

Hint & Explain

U can pass also nothing to the vararg argument

Vararg accepts both a sequence of integers and an array of integers.
