It uses Dual-Pivot Quicksort algorithm for sorting. Its complexity is O(n log(n)). It is a static method that parses an array as a parameter and does not return anything. Other inbuilt java methods allow you to sort your arrays. To use the sort method of arrays, you first need to reference a Java library called Arrays.
