Why does Java's Arrays.sort method use two different sorting algorithms for different types?
Java 6's Arrays.sort method uses Quicksort for arrays of primitives and merge sort for arrays of objects. I believe that most of time Quicksort is faster than merge sort and costs less memory. My experiments support that, although both algorithms are O(n log(n)). So why are different algorithms us...

Implementing a functional variant of quicksort that operates on arrays defeats the purpose. Arrays are never immutable.
The “proper” functional implementation of quicksort uses immutable lists. It is of course not in-place but it’s got the same worst-case asymptotic runtime (O(n^2))...
