Final Course Project: Inventory Management System

🚀 Project Overview

You will build a professional Inventory Management System for a retail warehouse. This project integrates Java's strong typing, deep Object-Oriented principles, Exception Handling for robust logic, and the Collections Framework for data storage.

Problem Statement

A warehouse needs to track its products, suppliers, and stock levels. The system should allow adding new items, updating quantities when sales happen, and generating a "Low Stock" alert for items below a certain threshold.

Project Objectives

• Use an ArrayList<Product> to manage items.
• Implement Encapsulation to protect product pricing and stock counts.
• Use Inheritance to distinguish between Perishable and Non-perishable goods.
• Handle Custom Exceptions for scenarios like "Out of Stock".

Core Features

1. Dashboard: View all current inventory in a tabular format.
2. Add/Remove: Dynamically manage the product list.
3. Sales Engine: Deduct stock when an item is sold; throw error if stock is 0.
4. Supplier Tracking: Use a HashMap to link Products to their Suppliers.
5. Search & Filter: Find products by ID or Category.

Development Steps

1. Define an abstract Item class.
2. Inherit Electronics and Food classes from Item.
3. Create a WarehouseManager class that contains the ArrayList.
4. Implement the Scanner logic for a text-based user interface.
5. Write a method that iterates through the list and prints alerts for items with quantity < 5.
