![]() It is also last node so tail's next will point to null It is first node so prev will point to null The newNode is pointed by both head or tail ![]() Check whether our doubly linked list is empty or not Create addNewNode() method to add a node into a list Initialize head and tail for the doubly linked list ![]() In the given program, each line of code is defined through comments so that you can understand the code easily. The user stores the information, and prev and next contain the previous and next nodes of the doubly linked list. The data can be of int, String, or float and prev and next are of the Node type. The class contains three properties, i.e., data, prev, and next. Let's understand some basic programs of doubly linked list: Creating a doubly linked listįor creating a node, we have to create a class for creating a Node type. ![]() A doubly linked list program can be of creating a doubly-linked list, inserting a node, or deleting a node. In C and C++, it is very easy to maintain a doubly linked list using pointers, but in Java, there is no concept of pointer that makes its construction a little bit tricky. Next → ← prev Doubly Linked List Program in Javaĭoubly linked list programs are very complex programs to understand because the node of the doubly linked list contains two fields, previous and next.
