Integer array reverse

Question

      * arrayReverse method
      * intArray = {1,2,3,4,5,6,7,8,9,10}, this method is supposed to
      * reverse the values (e.g. 10,9,8,7,6,5,4,3,2,1..)
      public void arrayReverse()
                for (int index = 0; index < 4; index++)
                     for (int scan = 9; index > 5; scan--)
                         int temp = intArray[index];
                         arrayChange(index, intArray[scan]);
                         arrayChange(scan, intArray[temp]);
       }I've been attempting this for the better part of my evening and can't seem to make out what I'm doing wrong.
I know for instance, that my for loops are at fault; but I haven't made one step forward in switching any of the values.
any help would be greatly appreciated
v/r,
mess

Answer 1

Suggestions:
Instead of
int next = 9;Do
int next = intArray.length;And instead of
for (int index = 0; index < 4; index++)do
for (int index = 0; index < intArray.length/2; index++)This will make your code work no matter if intArray has 10 elements, 3 elements or 25 elements. And it's what I meant when I said to get rid of the magic numbers.
