Inventory Management System

The Inventory Management System is a simple Java application designed to manage a list of items with their associated quantities and prices. It allows users to add, update, remove, and display items in the inventory. This project demonstrates basic object-oriented programming concepts, including the use of collections like TreeMap, HashMap, and ArrayList.

Features

  • Add new items to the inventory.
  • Update existing items' quantity and price.
  • Remove items from the inventory.
  • Display all items in the inventory.
  • Use of multiple data structures to manage and manipulate inventory data (TreeMap, HashMap, ArrayList).

Technologies Used

  • Java: Programming language for the core application.
  • Collections: TreeMap, HashMap, ArrayList for inventory management.
  • Scanner: For user input.

Project Structure

The project is composed of two main classes:

  • Item.java: Represents the details of an inventory item (name, quantity, price).
  • InventoryManagementSystem.java: Manages the inventory, handling user input and performing CRUD (Create, Read, Update, Delete) operations on items.

How to Run the Program

  1. Ensure you have Java Development Kit (JDK) installed on your machine.

  2. Clone or download the repository from GitHub.

  3. Navigate to the project folder and compile the Java files using:

    javac InventoryManagementSystem.java

  4. Run the program with:

    java InventoryManagementSystem

  5. Follow the on-screen prompts to manage your inventory.
