How does the Iterator Pattern contribute to code maintainability?
By centralizing object creation logic.
By defining a family of algorithms and making them interchangeable.
By encapsulating the iteration logic and abstracting the aggregate structure, making changes to either independently easier.
By providing a global point of access to a single instance.
How does the State Pattern typically handle state transitions?
State transitions are determined by external events only.
A separate 'State Manager' class controls all transitions.
The 'Context' object directly modifies its internal state.
State objects have methods to trigger transitions to other states.
What is a key advantage of using the Builder Pattern?
It enforces the creation of immutable objects.
It reduces the number of classes needed to represent the object.
It improves code readability and maintainability by separating construction logic.
It eliminates the need for constructors.
Which real-world scenario is well-suited for the Composite pattern?
Managing a database connection pool.
Representing a file system with directories and files.
Creating a thread-safe singleton object.
Implementing an undo/redo mechanism.
Which of these is NOT a potential benefit of using the Composite pattern?
Flexibility in object structure.
Uniform treatment of objects.
Increased code complexity.
Open/Closed Principle adherence.
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.
What could be a potential drawback of applying the Composite pattern?
It violates the Single Responsibility Principle.
It can make it harder to restrict operations on specific component types.
It increases coupling between objects.
It makes adding new leaf objects difficult.
Which of these relationships best describes the Composite pattern?
Both Inheritance and Composition
Realization
Inheritance
Association
What is the primary goal of the State Pattern in object-oriented programming?
To manage and transition between different states of an object.
To define a family of algorithms and encapsulate each one.
To create objects without specifying their concrete classes.
To provide a way to access elements of an aggregate object sequentially.
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.
Managing a large collection of immutable data points.
Representing characters in a document editor.
