Merge sort java program: Merge sort algorithm is a divide and conquers approach based algorithm, with time complexity n log(n) order, quicksort. An input array to sort is divided into two equal parts until they are divided into small enough arrays those are sorted and can be merged.
In Merge sort java program there are two methods, merge, and sort. Merge method merges two sorted arrays into one sorted array. sort method first divides the input array into the smallest arrays that can be merged and calls the merge to merge method. sort method is recursive in nature.
