What is time complexity for the following function?

public void printAllPossibleOrderedPairs ( int[] arrayOfItems)
{  
   for (int firstItem : arrayOfItems)
   { 
       for (int secondItem : arrayOfItems)
       {
           int[] orderedPair = new int[] { firstItem, secondItem};
           system.out.print( Arrays.toString(orderedPair));
       }
   }
}
