In this post, We will learn about How to represent the Doubly Linked List in Java?

We can easily understand how the Doubly Linked List represented with the help of the below diagram:

Doubly Linked List

  • It is called two ways Linked List.
  • In Doubly Linked List We can navigate in both forward and backward direction that is not possible in Singly Linked List.
  • A node in a Singly Linked List cannot be removed unless we have the pointer to its predecessor but in a Doubly Linked List, We can move node even if we do not have the previous node’s address.

Since each node has a left pointer pointing to the previous node and can move backward.

The primary disadvantages of doubly-linked List are:

  • Each node has an extra pointer which requires more space.
  • The intersection or deletion of a node takes a bit longer because of more pointer operations.
