It does not have any pointer that points to the previous node. That means we can traverse the list only in forward direction.

The implementation of doubly linked list in Java comprises of creating a doubly-linked list class, the node class and adding nodes to the doubly linked list. The addition of new nodes is usually done at the end of the list. The below diagram shows the addition of the new node at the end of the doubly linked list. split pdf by file size
