The important thing to remember when comparing LinkedList and ArrayList is that linked lists are more faster when inserting and removing at random locations in the list multiple times. For that, you must work through a ListIterator. Tree is a type of graph) and you know beforehand that the nodes will have at most one or two adjacent nodes and the total number of nodes in the graph can be quite large.Īlthough both ArrayList and LinkedList allow insertion/deletion in the middle through similar operations (ie by invoking add(int index) or remove(index)), these operations do not offer you the advantage of O(1) insertion/deletion for a LinkedList. This becomes important if you plan to keep an adjacency list of nodes for each node in the graph (graph can be like a TreeSet. These do affect the performance of a application if not analyzed properly.Īn empty LinkedList takes 2-3 times less memory than an empty ArrayList. Then they can very important for any small application that processes huge amount of data. These differences are not so important for any small applications that processes small amount of data. There are some differences between an and. ![]()
