In a language like Java, how is object cloning often achieved within the Prototype Pattern?
By using the Object.assign() method.
Object.assign()
By directly copying object properties.
By implementing the Cloneable interface.
Cloneable
By using the spread operator.
spread
Which of these scenarios is a good candidate for using the Proxy Pattern?
Representing a complex object hierarchy in a simplified manner.
Defining a one-to-many dependency between objects.
Iterating over a collection of objects without exposing its structure.
Creating objects that are only instantiated when actually needed.
What is the primary purpose of the Iterator Pattern in software development?
To define a family of algorithms, encapsulate each one, and make them interchangeable.
To ensure that a class has only one instance and provides a global point of access to it.
To create objects from a class without specifying the exact class to create.
To provide a way to access elements of an aggregate object sequentially without exposing its underlying representation.
In the Builder Pattern, what is the product?
The complex object being constructed.
The director class that orchestrates the building process.
The interface that defines the building steps.
The concrete builder class that assembles the object.
Which of the following is NOT a core participant in the Iterator Pattern?
Aggregate
Iterator
Factory
ConcreteIterator
In the Builder Pattern, what is the role of the 'Director'?
It defines the abstract steps for building the object.
It constructs the actual object using the Builder.
It provides an interface to access the built object.
It represents the complex object being built.
How does the Iterator Pattern handle situations where the underlying collection might be modified during iteration?
It relies on the client code to manage synchronization and prevent issues.
It creates a copy of the collection to ensure data integrity during iteration.
It generally does not handle this directly; safeguards like concurrent modification exceptions might be needed.
It automatically prevents any modifications to the collection while iteration is in progress.
What is the primary goal of the Prototype Pattern?
To provide a way to access elements of an aggregate object sequentially.
To avoid costly creation of objects by copying existing ones.
To ensure a class has only one instance.
What is the primary purpose of the Proxy Pattern in software design?
To allow objects to be notified of changes in other objects.
To define a family of algorithms and encapsulate each one.
To control access to an object, potentially restricting its use.
To provide a simplified interface to a complex subsystem.
In a typical Iterator Pattern implementation, what is the role of the 'ConcreteIterator' class?
It creates objects without exposing the instantiation logic to the client.
It implements the Iterator interface and provides the concrete implementation for iterating over a specific aggregate object.
It represents the collection of objects being iterated over.
It defines the interface for accessing and traversing elements.
