What is a potential drawback of using the Adapter Pattern?
It is not suitable for adapting interfaces with many methods.
It can lead to performance issues due to the overhead of adaptation.
It violates the Open/Closed Principle.
It can make the code more complex, especially with multiple adapters.
What is a potential downside of overusing design patterns?
Increased code readability
Reduced code complexity
Unnecessary complexity and abstraction
Improved code performance
Which principle of object-oriented design does the Decorator Pattern promote most effectively?
Liskov Substitution Principle
Open/Closed Principle
Dependency Inversion Principle
Single Responsibility Principle
How does the Factory Method pattern typically handle the instantiation of concrete objects?
It delegates the instantiation to separate builder classes.
It uses a chain of conditional statements within the factory method.
Subclasses override the factory method to provide their own creation logic.
It relies on dependency injection to provide concrete object instances.
How does the Decorator Pattern achieve the dynamic addition of responsibilities?
By using reflection to alter the behavior of methods during execution.
By composing objects, where decorators wrap the component and delegate to it.
By using inheritance to create subclasses with extended functionality.
By modifying the source code of the decorated object at runtime.
Which of these is NOT a benefit of using design patterns?
Facilitated code reuse
Enhanced code maintainability
Increased code duplication
Improved code readability
In the Observer pattern, how are observers typically notified of changes?
By sending an email notification.
Using a message queue.
By directly accessing the subject's state variables.
Through a method call on the observer object.
In which scenario would the Factory Method pattern be a more suitable choice than the Simple Factory pattern?
When you want to avoid using inheritance in your object creation process.
When object creation logic is simple and doesn't require subclass-specific variations.
When you have a fixed set of objects to create and no need for future extensions.
When you anticipate the introduction of new product types in the future.
How does the Strategy Pattern promote the Open/Closed Principle?
It reduces the need for inheritance, making the codebase more flexible.
It allows adding new strategies without modifying the existing Context class.
It promotes code reuse by allowing strategies to be shared across multiple contexts.
It prevents modification of existing strategies, ensuring their integrity.
Which of these is NOT a benefit of using the Facade Pattern?
Shielded clients from the complexities of the subsystem.
Reduced coupling between client code and the subsystem.
Increased code complexity and difficulty in understanding.
Improved code readability and maintainability.
