Linked List Project

This project implements a singly linked list in Java with the following methods:

append: Adds a new node to the end of the linked list.

deleteNode: Deletes a node from the linked list.

isEmpty: Returns true if the linked list is empty, false otherwise.

Usage

To use the linked list, create an instance of the LinkedList class and call the methods as needed. Here's an example:

public static void main(String[] args) {
        LinkedList l1 = new LinkedList(); 
        LinkedList l2 = new LinkedList(); 

        l1.display();

        l1.append(2);
        l1.append(4);
        l1.append(3);
        l1.display();

        System.out.println();
        l2.append(5);
        l2.append(6);
        l2.append(4);
        l2.display();

        System.out.println();
        LinkedList l3 = addtwoLinkedList(l1, l2);

        l3.display();


    }
}

This will print

Empty
2 -> 4 -> 3 ->
5 -> 6 -> 4 ->
7 -> 0 -> 8 ->

Unit Tests

The UnitTests class contains tests for the linked list methods. It also includes a function to add two non-empty linked lists representing two non-negative integers stored in reverse order and return the sum as a linked list. The code above is taken from this file.
