![]() ![]() ArrayList provides O(1) performance for get(index) method but remove is costly in ArrayList as we need to rearrange all elements. Getting elements from ArrayList with index is pretty fast. DifferencesĪrrayList is backed by Array while LinkedList is backed by LinkedList. It means they will throw ConcurrentModificationException if collection is modified structurally once Iterator is created. Iterator of both LinkedList and ArrayList are fail-fast. So they maintain insertion order of elements, i.e., first element will be added on first position.ĪrrayList and LinkedList also allow duplicates and null value. Therefore we can pass either ArrayList or LinkedList if a method accepts List interface.īoth ArrayList and LinkedList are not synchronized, it means we cannot share them among multiple threads in a concurrent environment without external synchronization.ĪrrayList and LinkedList both are ordered collection. Similaritiesīoth ArrayList and LinkedList are implementations of List interface. In this tutorial we will discuss what are the similarities and differences found between ArrayList and LinkedList. ArrayList and LinkedList are two popular concrete implementations of List interface from Java’s popular Collection framework.īeing List implementations both ArrayList and LinkedList are ordered, index based and allows duplicate. ![]()
