Why is the answer 2?

Question

What is the output of this code?
int arr[ ] = new int[3];
for (int i = 0; i < 3; i++) {
arr[i] = i;
}
int res = arr[0] + arr[2];
System.out.println(res);

Can someone explain to me why the answer is 2 please?

The explanation is in the code but the for loop is building the array arr
So
arr[0] = 0
arr[1] = 1
arr[2] = 2

So
arr[0] + arr[2] equals 2
res = 2
