Building Linked List Class

In order to build a linked list class, you'll typically define a structure or a class to represent the nodes of the linked list. Each node should contain two essential members:

Value: The actual data or value that the node holds.
Address (Pointer to the Next Node): A reference or pointer to the next node in the linked list.

Building Node class

// Node class represents a single node in the linked list
public class Node {

    int data;   /*Data or value held by the node*/
    Node next;  /*Reference to the next node in the linked list*/

    /* Constructor to initialize a node with a given value */
    public Node(int data) {
        this.data = data;
        this.next = null; /*By default, the next node is set to null*/
    }
}

Building Linked List Class

Develop a separate linked List class to manage the overall structure of the linked list.
Include a reference to the head node and a variable to keep track of the list size.

public class linkedList {
  Node head;   /*Stores the first node of the linked list*/
  int size;    /*Stores the length of the linked list*/

  public  void insertNode(int data)
  {
    /*...............................
      Implementation 
    .................................*/
  }

  public void getLength()
  {
    /*...............................
      Implementation 
    .................................*/ 
  }

  public  void display()
  {
    /*...............................
      Implementation 
    .................................*/ 
  }

  public Node deleteNode(Node head, int position)
  {
    /*...............................
      Implementation 
    .................................*/
  }

}

Building Main class

Create a Main class to serve as the entry point of the program.
Construct a Main class and create instance of linkedList class in order to perform all the operations.

class Main{
    public static void main(String args[])
    {
        linkedList list = new linkedList();
        /*.....................................
        perform operations : insertion, deletion, etc..
        ........................................*/
    }
}
