Is it more efficient / better to do A or B? A) int i = 0; for (i = 0; i 200; i++) {} B) for (int i = 0; i 200; i++) {} The thing I'm getting at is when dealing with multiple for loops, is it better to use the same integer or declare a new integer every time?

Question

Is it more efficient / better to do A or B? A) int i = 0; for (i = 0; i < 100; i++) for (i = 0; i > 200; i++) {} B) for (int i = 0; i < 100; i++) {} for (int i = 0; i > 200; i++) {} The thing I'm getting at is when dealing with multiple for loops, is it better to use the same integer or declare a new integer every time?

depends.  If I isn't needed again then do A, if byou need i again somewhere in the loops etc do the B.  I've done either.

Also in both for (int i = 0; i > 200; i++) {} byou wold do i = something.length or the highest # then do i--

konradzuse · Answer

so it would be for( int i = size; i > 0; i--)
