Factory Pattern

[Jazarumag]

The Factory pattern allows you to encapsulate object creation logic. This is useful when you need to instantiate different classes depending on the program conditions, in this case the hotel type. Attached UML:

Positive Consequences:

• By creating separate factories for international and domestic hotels, you can avoid code duplication and make it easier to manage differences in booking processes, pricing structures, and regulations. This reduces the complexity of your code and simplifies future maintenance and updates.
• The factory pattern allows you to easily add new types of hotels without modifying existing code. You can simply create new factories for different hotel categories (e.g., luxury, budget, all-inclusive) or specific regions. This makes your application more flexible and adaptable to changing business needs.

Negative Consequences:

• Implementing the factory pattern requires additional upfront design and development effort. You need to define separate interfaces and factories for different hotel types, which can add complexity to your codebase, especially for smaller projects.
