Principle and implementation of double ended linked list of Java data structure

• Java

This paper describes the principle and implementation method of double ended linked list of Java data structure. Share with you for your reference, as follows:

1、 Overview:

1. When is a double ended linked list:

In the linked list, keep the linked list of the last join reference

2. Insert from head

To judge the linked list, if it is empty, set the tail node as the newly added node

3. Insert from tail

If the linked list is empty, set the head node as the newly added node directly; otherwise, set the last node of the tail node as the newly added node

4. Delete from header

Judge whether the node has a next node. If not, set the node to null

2、 Concrete implementation
