What happens?

Is there any difference in this code? If there is an SomeObject array called array...
SomeObject object = null;
for (int i = 0; i < array.length; i++) {
object = array[i];
...some processing...
}
or........
for (int i = 0; i < array.length; i++) {
SomeObject object = array[i];
...some processing...
}

I think no. 2 is wrong, you have to declare before the loop.

Either form is acceptable. The second form creates a bunch of unneeded pointers but since they are on the stack and not the heap, it isn't a big deal.

both are correct and work fine i just didn't know if there was a performance difference one way or the other

[Aaron Webb]

cool thats what i was wondering...thanks

Well, did you try to benchmark the two? That would give you the only authentic answer...

How do you benchMark?
Is it Just a way of checking how much time each loop takes.Do you do it using time functions.?
Or is there someother method to do this?
Thanks.
