Hi,
Is there any performance issues with declaring variables inside a loop? Please see the following examples

Eg:1

for (int i=0;i<10;i++) {
x x1 = (x) list.get(i);
}

Eg:2

x x1 = null;
for (int i=0;i<10;i++) {
x1 = (x) list.get(i);
}

What is the performance difference between these two strategies? Which one is better and why?
