Variable Length Argument List (using Get)

I cannot seem to understand the concept of variable length argument lists. When I do a bit of research, it makes sense, but I can't figure out this question to save my life.

What is the result of the following call?

get(1, 2, 3, 4, 5, 6, 7); // The Call

public int get(int ... a) {
    return a[2];
}

My answer was "2" which is the only thing that makes sense to me. The other options were 1, 3, or 4. Thanks for your time.

Solution

  • Arrays are zero based. Which is to say the first item is at position 0, the second at position 1. So the item at position 2 in your case is the integer 3.
