Pros and cons come with every technical aspect and Doubly linked lists are no exception!
There are various parameters on which doubly linked lists are quite impressive for the developers.
But do you know what a doubly Linked list in data structure is? If not, this article will be a game-changer for you. Every concept of doubly Linked lists will be elaborated on throughout the article.
We have included one of the major issues i.e. identifying the difference between ArrayList and linked lists in the article to resolve this issue for you!
But, before moving further into the details, let’s have a glance at what is a doubly linked list in data structure.
What is a Doubly Linked list in Data structure?
As the name suggests, it is linked from both ends!
Linked lists contain chains of elements linked to each other through pointers. Usually, the chain moves in one direction i.e. right or left!
However, in the case of Doubly linked lists, each element of the list comes with two pointers attached to both i.e. left and right ends of the memory block where the element is stored.
The left pointer points toward the previous node or the previous element in the list whereas the right pointer indicates the presence of the next element in the linked list.
Do you think this is the same case for ArrayList as well? Let’s have a brief about how
LinkedList and ArrayList differ from one another.
Difference between ArrayList and LinkedList
The main difference is the data storage type!
ArrayList contains an array of elements stored within the list. You can call out any element through a variable in the case of ArrayList. However, this is not the case for linked lists!
In LinkedList, the data is stored in memory blocks that are placed in the form of a list and implemented with a queue approach.
Although it’s easy to insert or eliminate any element from the linked lists, you can not get access to the location of a certain element via variable.
This is one of the major differences between linked lists and ArrayList. Other differences include allocation of memory, element access, and others.
Now that you can easily differentiate between the two, it’s time to move to the benefits of using a doubly linked list in the data structure.
