The Pharmacy Management System is a comprehensive Java application developed as a final project for the Data Structures and Algorithms (DSA) and Java course. This system provides a complete solution for pharmacy management, including inventory control, customer management, medicine tracking, and sales processing.
- 🏥 Medicine Management: Add, search, update, and remove medicines from inventory
- 👥 Customer Management: Register customers, manage profiles, and track purchase history
- 🛒 Shopping Cart: Easy-to-use interface for adding medicines to cart and checkout
- 📊 Inventory Management: Track stock levels and receive low stock alerts
- 💰 Transaction Processing: Process sales and maintain transaction history
- 🧾 Billing System: Generate detailed bills for customers
- 💾 Data Persistence: Save and load data using CSV files

- MVC Architecture: Clean separation of concerns with Model-View-Controller pattern
- Custom Data Structures: Implementation of LinkedList, Queue, and MergeSort algorithms
- File-based Storage: CSV-based data persistence for easy deployment
- Console UI: User-friendly command-line interface with intuitive navigation
- Modularity: Well-organized code structure with clear separation of functionalities
- Error Handling: Robust error and exception handling throughout the application
- Java Development Kit (JDK) 8 or higher
- Git (optional)

Clone the Repository
git clone https://github.com/Anuj-er/PharmacyManagementSystem-Java-DSA.git cd PharmacyManagementSystem -
Compile the Project
javac -d output src/Main.java src/controller/*.java src/model/*.java src/data_structure/*.java src/util/*.java src/storage/*.java src/config/*.java
-
Run the Application
java -cp output Main
After launching the application, you'll be presented with the main menu:
-
For Pharmacy Staff:
- Medicine Management: Add, update, and remove medicines
- Customer Management: Manage customer profiles
- Inventory Management: Update quantities and check low stock
- Transaction History: View past transactions
-
For Customers:
- Browse available medicines
- Search for specific medicines
- Add medicines to cart
- View and manage cart
- Checkout and receive bills
This project implements several custom data structures:
- MyLinkedList: A generic linked list implementation used throughout the system for dynamic data storage
- MyQueue: A queue implementation used for processing orders
- MergeSort: An efficient sorting algorithm used for sorting medicines and transactions
Example implementation of MyLinkedList:
public class MyLinkedList<T> {
private Node<T> head;
private int size;
// Node inner class
private static class Node<T> {
T data;
Node<T> next;
Node(T data) {
this.data = data;
this.next = null;
}
}
// Add element to the list
public void add(T element) {
Node<T> newNode = new Node<>(element);
if (head == null) {
head = newNode;
} else {
Node<T> current = head;
while (current.next != null) {
current = current.next;
}
current.next = newNode;
}
size++;
}
// Other methods: remove, get, size, isEmpty, etc.
