Java Program to create and display a singly linked list. The singly linked list is a linear data structure in which each element of the list contains a pointer which points to the next element in the list. Each element in the singly linked list is called a node.

A Linked List is a linear data structure consisting of a collection of Nodesthat are not stored in contiguous but random memory locations. It is a commonly used data structure in Computer programs and helps us to build even more complex data structures like Stacks, Queues, Skip Lists, etc. A Linked List has the following features: 1. Each node of t...
A Singly Linked List is the most common form of a Linked List where each node contains a data field and a singlepointer to the next node in the list. The reference to the first node in the list is called the HEAD of the list. The pointer/reference/link field contained in the node is used to traverse to the next node and to its next node and so on t...
3.1. Creating a Singly Linked List
A singly linked list in java can be created by using a self-referential class. A self-referential class is one that holds a reference to itself. Below is a class SinglyLinkedList that encloses an inner self-referential class Node having two fields, a data field which is an integer and a “next” field which is of the type Node. The outer class also holds the reference/pointer/link to the HEAD of the list. SinglyLinkedList.java
3.2. Inserting Nodes Into a Singly Linked List
There are three cases to consider for inserting a node into a singly linked list. Adding a node to the : 1. Beginning of the list. 2. End of the list. 3. Specified position in the list.
3.3. Deleting Nodes From a Singly Linked List
Deleting a node from a singly linked list can be a little complex as the node to be deleted can be the first node, the last node, or a node in the middle of the list. Let us discuss each case. 1. First Node:If the node to be deleted is the first node itself, we assign the reference of the next of the HEAD node to the HEAD node. Delete the first node 1. Last Node or Any Other Node:To delete any other node in the list, we traverse the list keeping track of the previous and current nodes in the...
No direct access to individual elements is possible. The only way is to start from the HEAD and follow the references in each node to reach the desired node.A singly linked list uses more memory as compared to an array to store the reference to the next node.Some of the applications of Singly Linked Lists are : 1. To implement complex data structures i.e. Stacks , Queues and Skip Lists. 2. To implement the adjacency list representation of a Graph.
In this tutorial, we learned about how to create a Singly Linked List in Java with several cases of add and delete operations. Also, we saw the limitations of Arrays and the advantages, disadvantages, and applications of using a Singly Linked List.
Learn how to create and manipulate a singly linked list in Java with live code and examples. A singly linked list is a linear data structure where each node has a data field and a pointer to the next node.
