What is a potential drawback of using the Adapter Pattern?
It violates the Open/Closed Principle.
It can lead to performance issues due to the overhead of adaptation.
It can make the code more complex, especially with multiple adapters.
It is not suitable for adapting interfaces with many methods.
Which of these scenarios would be a suitable use case for the Decorator Pattern?
Implementing a logging system that can be added to different parts of an application.
Representing a family tree with complex relationships between members.
Creating different types of vehicles with varying features.
Managing the state of an object throughout its lifecycle.
In a Facade Pattern implementation, what is the role of the Facade class?
It restricts access to the subsystem, preventing any external interaction.
It defines the interfaces for all classes within the subsystem.
It directly implements the complex logic of the subsystem.
It delegates requests to appropriate subsystem classes and returns results.
In the context of the Decorator Pattern, what is the relationship between the 'ConcreteComponent' and 'Decorator'?
There is no direct relationship between them.
Both the Decorator and ConcreteComponent implement the same interface.
The Decorator inherits from the ConcreteComponent.
The ConcreteComponent inherits from the Decorator.
Which principle of object-oriented design does the Decorator Pattern promote most effectively?
Single Responsibility Principle
Dependency Inversion Principle
Open/Closed Principle
Liskov Substitution Principle
In the context of the Strategy Pattern, what does a 'Context' object typically do?
It implements the actual algorithms defined by the Strategy interface.
It maintains a reference to a Strategy object and delegates work to it.
It defines the interface for all Concrete Strategies.
It acts as a factory for creating Strategy objects.
What is a key characteristic of a well-implemented design pattern?
It introduces significant code complexity.
It eliminates the need for documentation.
It promotes code reusability and maintainability.
It is tightly coupled to a specific problem domain.
What is the primary intent of the Facade Pattern in software design?
To expose low-level implementation details to clients.
To provide a simplified interface to a complex subsystem.
To define a family of algorithms and encapsulate each one.
To create new functionalities within existing classes.
What is the primary intent of the Factory Method pattern in software development?
To create objects directly within a class, exposing instantiation logic.
To delegate object creation to subclasses, promoting extensibility.
To enforce strict object creation rules through a central factory class.
To reduce code duplication by reusing object creation code across classes.
How does the Decorator Pattern differ from traditional inheritance for extending functionality?
Inheritance allows for dynamic extension at runtime, while Decorator does not.
Decorator provides more flexibility by allowing the combination of multiple functionalities at runtime.
Inheritance is generally preferred over Decorator due to its simplicity.
Decorator modifies the original class, while inheritance creates new subclasses.
