Java: How many times is arr.length called in a for-loop?

Question

If arr is an array of size 10, in the following code block, how many times is arr.length accessed?

for (int i = 0; i < arr.length; ++i);

Once? Or every time it loops?

Thanks everyone! Here's what I ended up doing:

final int len = arr.length;
for (int i = 0; i < len; ++i);

Answer 1

Eleven times....

10 times, the statement i < arr.length evaluates to true.
1 time it evalutes to false and the loop ends.
