Hi all,

Is there a way to transform an Integer[] to an int[] and vice-versa without looping through the array ?

I daresay that is no possible.

If what you actually mean is that you do not want to write the algoritm then use Jakarta Commons ArrayUtils class, it has a method int[] toPrimitive(Integer[])

And this is what the algorithm does:



I hope that helps!
 
It is sorta covered in the JavaRanch Style Guide.
