I have a question about looping through an array, in Processing but also programming in general.
Lets say I have 2 arrays with large amount of data. I need to loop through them, something like this:

1. for (int i = 0; i < myArray1.length; i++) {
2.       for (int j = 0; j < myArray2.length; j++) {
3.             ...
4.       }
5. }

If I'm correct int i & j are recreated every time this code runs, and the test expression (array length) is collected every iteration. So instead, would this be faster?

1. int i;
2. int j;
   
3. int length1 = myArray1.length;
4. int length2 = myArray2.length;
5. for (i = 0; i < length1; i++) {
6.       for (j = 0; j < length2; j++) {
7.             ...
8.       }
9. }

Thanks in advance.
