Circular Singly Linked List in Java | Full Example & Explanation Circular Singly Linked List in Java – Full Example with Step-by-Step Explanation Introduction A Circular Singly Linked List (CSLL) is similar to a Singly Linked List, but the next pointer of the last node points back to the head node. This creates a circular structure, allowing continuous traversal without null termination. Java Code with Step-by-Step Explanation // Node class for CSLL class Node { int data; // Stores node value Node next; // Reference to next node Node(int data){ this.data = data; this.next = null; } } Step: Define a node with data and next . In CSLL, next of the last node will point back to the head. // Circular Singly Linked List class class CircularSinglyLinkedList { Node head; // start of the list // Insert at end public voi...

Doubly Linked List in Java | Full Example Code & Explanation Doubly Linked List in Java – Full Example with Step-by-Step Explanation Introduction A Doubly Linked List (DLL) allows navigation forward and backward. Each node has data , a prev pointer to the previous node, and a next pointer to the next node. This makes insertion and deletion faster than Singly Linked List in the middle of the list. Java Code with Step-by-Step Explanation // Node class for DLL class Node { int data; // Stores node value Node prev; // Reference to previous node Node next; // Reference to next node Node(int data) { // Constructor this.data = data; this.prev = null; this.next = null; } } Step: We define the node structure. Each node knows its data , prev and next . // DLL class class DoublyLinkedList { Node head; // start o...
