Java Review Question

[toad]

I am working on a review for my midterm and need some help with a problem.

Code:

 This is the question:

if array a is int[] a = {1, 2, 3}, what is a[0] - a[2]?

a.	1
b.	2
c.	3
d.	None of the above

I am guessing that the answer is: b

Anyone know if I am right? If it is not "b" why is it not "b"?

[JavaBean]

a[0] is 1 and a[2] is 3. So the answer is -2 which is "d".
