📚 Java Book Store: Session-Based Shopping Cart

📝 Project Overview

This project involved maintaining and extending a legacy Java Web Application. The primary goal was to implement missing CRUD functionality within a session-based shopping cart system.

🛠️ Technical Challenges & Solutions

1. Session State Management

• Challenge: The original application could add items to a cart, but users had no way to adjust quantities or remove items without clearing the entire session.
• Implementation: Leveraged the HttpSession API to manage a collection of book objects, ensuring state persistence as the user navigated the storefront.

2. Implementing Cart CRUD Operations

• Update: Developed logic to synchronize the quantity input from the UI with the backend session object.
• Delete: Implemented a removal trigger that identified specific book IDs within the session collection and updated the total cost dynamically.

🎓 Learning Outcomes (Apprenticeship Context)

This was a guided project completed during my software development apprenticeship (circa 2022). It served as a deep dive into:

• Java Servlets & JSP: Understanding the request-response cycle in a web environment.
• Git Workflow: Using branch-based development to implement modular features (Module 1-3).
• Legacy Codebases: Navigating and modifying code written by other developers.
