Phone List Creator via Java

Title: Implement a Phone List using a Singly Linked List
Objectives
The goal of this assignment is to design and implement a phone list application
using a singly linked list data structure in Java. You will create a linked list where
each node represents a contact with a person's name and phone number. You are
required to implement the following functionalities: add, display, search, and delete
contacts.
The Problem
You are tasked with developing a phone list that stores contacts using a singly
linked list. Each contact will contain a name and a phone number. You will
implement methods to add new contacts, display all contacts, search for a contact
by name, and delete a contact from the list.
Requirements:
1. Data Structure:
o Implement a class ContactNode to represent a contact. Each ContactNode should contain:
 A name (String).
 A phone number (String).
 A reference to the next ContactNode.
o Implement a class PhoneList that manages the linked list of contacts. It should have a
reference to the head of the list.
2. Methods to Implement:
o addContact(String name, String phoneNumber):
 This method should add a new contact at the end of the linked list.
 If the list is empty, the new contact should become the first node (head).
 If the list is not empty, the method should traverse to the end and add the new contact.
o displayList():
 This method should traverse the entire list and print all the contacts.
 If the list is empty, it should display an appropriate message.
o searchContact(String name):
 This method should search the list for a contact by name.
 If the contact is found, it should print the contact's name and phone number.
 If the contact is not found, it should display a message indicating that the contact was
not found.
o deleteContact(String name):
 This method should delete a contact by name.
 If the contact to be deleted is the head, adjust the head to the next node.
 If the contact is found elsewhere in the list, remove it by adjusting the pointers of the
surrounding nodes.
 If the contact is not found, display a message indicating that no such contact exists.
Expected Output:
The program should display appropriate messages when performing the following operations:
 Adding a contact: e.g., "Contact added: Alice, 123-456-7890".
 Displaying contacts: e.g., "Name: Alice, Phone: 123-456-7890".
 Searching for a contact: e.g., "Contact found: Name: Alice, Phone: 123-456-7890" or "Contact with
name 'Bob' not found."
 Deleting a contact: e.g., "Deleting contact: Alice, 123-456-7890" or "Contact with name 'Bob' not
found."
 Handling empty lists: e.g., "Phone list is empt
