The idea is to get a sequential stream from elements of the specified array and sort it according to natural order or reverse order using a comparator. If you have a binary search tree that is self-balancing it is quite probably counter-productive to pre-sort the array. This class also contains a static factory Some of these terms are: Array Index: In an array, elements are identified by their indexes. Insertion Sort is a simple sorting algorithm that works wonders on small arrays. Array element: Elements are items stored in an array and can be accessed by their index. An algorithm like this just doesn't work without a sorted array .
