- A.
Iterator
- B.
Interpreter
- C.
State
- D.
Chain of Responsibility
- 12.Which Design Pattern has this Intent?

- A.
Decorator
- B.
Proxy
- C.
Visitor
- D.
Command
- 13.Which Design Pattern has this Intent?
- Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation.
- A.
Composite
- B.
Proxy
- C.
Iterator
- D.
Mediator
- 14.Which Design Pattern has this Intent?
- Provide a surrogate or placeholder for another object to control access to it.
- A.
Proxy
- B.
Memento
- C.
Mediator
- D.
Facade
- 15.Which Design Pattern has this Intent?
- Define the skeleton of an algorithm in an operation, deferring some steps to subclasses. _____ lets subclasses redefine certain steps of an algorithm without changing the algorithm's structure.
- A.
Bridge
- B.
Factory Method
- C.
Template Method
- D.
Builder
- 16.Which Design Pattern has this Intent?
- Compose objects into tree structures to represent part-whole hierarchies. Clients treat collections of objects and individual objects uniformly.
- A.
Composite
- B.
Prototype
- C.
Template
- D.
Iterator
- 17.Which Design Pattern has this Intent?
- Allow an object to alter its behavior when its internal state changes. The object will appear to change its class.
- A.
Composite
- B.
Strategy
- C.
Decorator
- D.
State
- 18.Which Design Pattern has this Intent?
- Define a family of algorithms, encapsulate each one, and make them interchangeable. _____ lets the algorithm vary independently from clients that use it.
- A.
Facade
- B.
Strategy
- C.
Abstract Factory
- D.

- A.
Bridge
- B.
Composite
- C.
Strategy
- D.
Factory Method

- A.
State
- B.
Observer
- C.
Command
- D.
Memento
