Design a Coffee Machine
State PatternStrategy PatternFactory PatternObserver Pattern
Design a coffee machine system that can prepare various beverages (coffee, tea, cappuccino, latte) based on predefined recipes, manage ingredient inventory (coffee beans, milk, water, sugar), allow user customization (sugar level, milk type), monitor ingredient levels with alerts, and handle the dispensing process with proper state management.
What You'll Build
- The coffee machine should support multiple beverage types (coffee, tea, cappuccino, latte) using the Factory Pattern to create beverage instances.
- The system should manage ingredient inventory (coffee beans, milk, water, sugar) with real-time quantity tracking.
- Each beverage should have a predefined recipe specifying required ingredients and their quantities.
- Before preparing a beverage, the system must validate that all required ingredients are available in sufficient quantities according to the recipe.
- The system should monitor ingredient levels and alert when any ingredient falls below a low threshold (e.g., 20% of capacity) using the Observer Pattern.
