Each node contains two fields, called links, that are references to the previous and to the next node in the sequence of nodes. This structure allows for efficient insertion or removal of elements from any position in the sequence during iteration.ĭoublyLinkedList: In computer science, a doubly linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Under the simplest form, each node is composed of data and a reference (in other words,a link) to the next node in the sequence. It is a data structure consisting of a group of nodes which together represent a sequence.
Each pointing to the next node by means of a pointer. LinkedList: In computer science, a linked list is a linear collection of data elements, in which linear order is not given by their physical placement in memory. Dynamic arrays overcome a limit of static arrays, which have a fixed capacity that needs to be specified at allocation.
After creation, its length is fixed.ĪrrayList: In computer science, a dynamic array, growable array, or array list is a random access, variable-size list data structure that allows elements to be added or removed. The length of an array is established when the array is created. Implemented following Data Structures using Java Language :Īrrays: An array is a container object that holds a fixed number of values of a single type.
