Using data structures from Java Collections is not allowed please implement your own data structures

A$.$ Objectives

$1.$ Use ArrayList to store items in the pantry.

$2.$ Implement methods to add, distribute, and search for items.

$3.$ Ensure the main method does not exceed $30$ lines of code.

$4.$ Implement the project correctly.

If you can can you please add meaningful identifiers, consistent indentation, explanatory

comments, and properly formatted output but also explain because I want to learn as much as possible.

B$.$ Description

You are tasked with developing a Food Pantry Management System for a college. This system

will help manage the inventory of a food pantry, allowing items to be added, distributed to

students, and searched.

System Requirements:

$1.$ Pantry Item Management:

$-$ Make a class PantryItem with attributes: name, quantity, and expiryDate.

$-$ Use an ArrayList to store PantryItem objects.

$2.$ Adding Items:

$-$ Implement a method to add items to the pantry. If an item already exists, update

the quantity.

$3.$ Distributing Items:

$-$ Implement a method to distribute items to students. If the requested quantity

exceeds availability, distribute the available quantity and update the inventory.

$4.$ Searching for Items:

$-$ Implement a method to search for items by name. Return the item details if found,

otherwise indicate that the item is not available.

$5.$ User Interface:

$-$ Develop a text$-$based menu interface to interact with the system. The interface

should include options to add items, distribute items, search for items, and exit the

program.

Edge Cases to Consider:

$$ Adding an item that already exists.

$$ Requesting more items than available.

$$ Searching for items not in the pantry.

$$ Handling invalid inputs gracefully.

Sample Program Flow:

$1.$ Start the program and display the menu.

$2.$ Select an option $($Add Item, Distribute Item, Search Item, Exit$).$

$3.$ Perform the selected action and display the result.

$4.$ Repeat until the user chooses to exit.

Sample Output:

Welcome to the Food Pantry Management System
