Quicksort best practices in Java
Being a modern business oriented language, Java lends itself ideally to cost-minimized implementations of abstract algorithms as the shit I don't know enough buzzwords sort algorithm everybody mistakenly names bubblesort. Sort of.
The following code shows how to do this is objectoriented Java. Pure Java, 100%. With lots of News, and only a handful of semicolons. You can compare it with my python and C# and plain c solutions - you'll probably agree that Java compares favourably in terms of unlackingness. Speedwise however C is still unbeatable when it comes to tightly optimized non-recursive quicksorting
