In a language like Java, how is object cloning often achieved within the Prototype Pattern?
By using the spread operator.
spread
By using the Object.assign() method.
Object.assign()
By directly copying object properties.
By implementing the Cloneable interface.
Cloneable
What is the primary purpose of the Builder Design Pattern?
To define a family of algorithms and encapsulate each one.
To create objects without exposing the instantiation logic.
To provide a way to access elements of an aggregate object sequentially.
To ensure only one instance of a class exists.
A Remote Proxy is typically used for:
Providing a local representation of an object in a different process.
Controlling access to the real subject based on user roles.
Caching the results of expensive operations for performance improvement.
Creating a placeholder for an object that hasn't been fully loaded.
Which of these is NOT a potential benefit of using the Composite pattern?
Flexibility in object structure.
Open/Closed Principle adherence.
Increased code complexity.
Uniform treatment of objects.
Which of these scenarios best exemplifies the use of the Prototype Pattern?
Implementing undo/redo functionality in a text editor.
Logging user actions in a system.
Managing the state of a traffic light system.
Creating multiple instances of game characters with slightly varying attributes.
What is a key advantage of using a 'Flyweight Factory' in the pattern?
It allows for dynamic loading and unloading of Flyweight objects.
It enforces the use of a single instance for each unique Flyweight.
It provides a centralized point for accessing and managing extrinsic state.
It simplifies the creation of complex Flyweight objects.
Which principle of object-oriented design does the Builder Pattern primarily promote?
Dependency Inversion Principle
Liskov Substitution Principle
Open/Closed Principle
Single Responsibility Principle
Which of these situations is LEAST suitable for applying the Flyweight pattern?
Implementing a particle system with thousands of visually similar particles.
Creating graphical objects for a user interface with varying themes.
Representing characters in a document editor.
Managing a large collection of immutable data points.
Which of the following is NOT a core participant in the Iterator Pattern?
ConcreteIterator
Factory
Aggregate
Iterator
In which scenarios is the Iterator Pattern particularly valuable?
When you want to provide a consistent way to traverse elements regardless of the collection type.
When multiple algorithms need to operate on a collection without knowledge of its internal structure.
When the internal representation of a collection is subject to change.
All of the above.
