![]() On the other hand manipulation with LinkedList is faster than ArrayList because it uses doubly linked list so no bit shifting is required in memory. If We need to insert or delete element in ArrayList, it may take O(n), as it internally uses array and we may have to shift elements in case of insertion or deletion. Manipulation with ArrayList is slow because it internally uses array. This is because ArrayList allows random access to the elements in the list as it operates on an index-based data structure while LinkedList does not allow random access as it does not have indexes to access elements directly, it has to traverse the list to retrieve or access an element from the list. ArrayList Method get(int index) gives the performance of O(1) while LinkedList performance is O(n). Search Operation in ArrayList is pretty fast when compared to the LinkedList search operation. LinkedList implements it with a doubly-linked list while ArrayList implements it with a dynamically re-sizing array. ArrayList and LinkedList are the Collection classes, and both of them implements the List interface. ![]()
