A doubly-linked list is a linked data structure that consists of a set of sequentially linked records called nodes. Each node contains two fields, called links, that are references to the previous and to the next node in the sequence of nodes. The beginning and ending nodes previous and next links, respectively, point to some kind of terminator, typically a sentinel node or null, to facilitate traversal of the list. If there is only one sentinel node, then the list is circularly linked via the sentinel node. It can be conceptualized as two singly linked lists formed from the same data items, but in opposite sequential orders.

A linked list is a linear data structure which consists of a group of nodes in a sequence. Each node contains two parts. The node of a singly linked list contains a data part and a link part. The link will contain the address of the Next node and is initialized to null.
Linked List in Java: How to Implement a Linked List in Java?
I just happened upon you're code after googling "doubly linked list". I'm implementing my own doubly linked list for an open source project and I'm too lazy to pull out a piece of paper to draw a picture, thus seeing someone else's implementation is quite helpful. I hope you don't mind me pointing out a small could be huge problem, that most casual programmers can usually ignore. Your code causes a memory leak.
In this tutorial, we will learn about the Java LinkedList in detail with the help of examples. The LinkedList class of the Java collections framework provides the functionality of the linked list data structure doubly linkedlist. Here, we have used the add method to add elements to the LinkedList. We will learn more about the add method later in this tutorial. Elements in linked lists are not stored in sequence.
