Insertion in a Singly Linked List
Explore the basic insertion techniques in singly linked lists including insert at head, insert at end, and insert after a given node. Understand step-by-step Java implementations and how these operations modify the list structure efficiently.

Introduction
In this lesson, we are going to briefly explain some basic operations and implement them using Java code. The three types of insertion strategies used in a Singly Linked List are:
- Insert at Head
- Insert at End
- Insert After
Insertion at Head
This type of insertion means that we want to insert a new element as the first element of the list. As the head always points to the first element of the list, insertion at head means that we are inserting the first element in the list. The following figure shows how InsertAtHead() happens in Singly Linked List:
