List<String> flowers = new ArrayList<String>();

My for loop currently looks like this...

for (int i = 0; i < flowers.size(); i++) {
...
}

OR should I change this to look like the code given below

int size = flowers.size();
for (int i = 0; i < size; i++) {
...
}

Which is more performant (assuming I have a large array of flowers), I am guessing it should be the latter.
