Portobello Manager - OOP Final Project

Project Overview

Portobello Manager is a Java console application for managing a second-hand store inventory. Items are organized in a hierarchical catalog (categories and products), with total price calculation and export to a text file.

Features

• Hierarchical Organization: Products and nested categories (Composite Pattern).
• Total Calculation: Recursive price sum for any category.
• Input Validation: Custom checked exceptions for invalid data (e.g. negative prices).
• Pricing Strategies: Full price or percentage discount on products (Strategy Pattern).
• Data Export: Catalog export via Singleton DataService to export_catalogo.txt.

Design Patterns

1. Composite — CatalogItem, Product, Category
2. Factory — CatalogFactory
3. Iterator — StoreIterator (DFS on the catalog tree)
4. Singleton — DataService
5. Strategy — PricingStrategy, RegularPrice, PercentageDiscount

Technologies

• Maven
• SLF4J / Logback
• JUnit 5
