🛠️ Technical Architecture

The application follows a Model-View-Service architecture to ensure separation of concerns. The UI is decoupled from business logic, and data persistence is handled via a dedicated layer.

Design Patterns Implemented

• Strategy Pattern: Used in the PricingPolicy engine. Calculation logic (Standard, Student, Premium) is injected at runtime, allowing for flexible pricing updates without modifying the core rental service.
• Singleton Pattern: Ensures thread-safe, single-instance access to data registries (Inventory, MemberRegistry) and the LanguageManager.
• Observer Pattern: Utilized extensively in the UI to update charts and tables in real-time when underlying data models change.
• Polymorphism: The inventory system treats Vehicle and Gear as interchangeable IRentable items, simplifying the rental logic.

Technology Stack

• Core: Java 17+, JavaFX (Programmatic DOM, No FXML)
• Persistence: Jackson (JSON Data Binding)
• Build Tool: Maven
• UI Assets: Ikonli (FontAwesome Pack), Custom CSS Theming

✨ Key Features

• Inventory Management: Unified system for tracking vehicles (RVs, Caravans) and gear (Tents, Backpacks).
• Smart Pricing: Automated cost calculation based on membership tiers (e.g., Student discounts, Premium surcharges).
• Financial Reporting: Live bar charts visualizing income trends over a 14-day rolling window.
• Localization: Instant runtime switching between English and Swedish ResourceBundles.
• Dynamic Theming: CSS-driven Dark/Light mode toggle.
