Difference Between Arrays.sort() and Collections.sort()

Date: 2024-03-07

Java offers two primary methods for sorting data: Arrays.sort() and Collections.sort(). Arrays.sort() efficiently sorts primitive type arrays and objects using quicksort or mergesort, relying on compareTo() or custom comparators. Collections.sort() works on List implementations, also using compareTo() or custom comparators for ordering. Both provide ascending order sorting, offering convenient and efficient solutions for different data structures. Choosing between them depends on whether you're working with arrays or collections.
