Structural Design Pattern Design Patterns and Principles Chapter 2 Part 2

Question 1

• are a subset of design patterns in software development that focus on the composition of classes or objects to form larger, more complex structures.
• They help in organizing and managing relationships between objects to achieve greater flexibility, reusability, and maintainability in a software system

Answer 1

Structural design patterns

Question 2

is a structural design pattern, it allows you to make two incompatible interfaces work together by creating a bridge between them.

Answer 2

Adapter Method

Question 3

The intent of this pattern is to decouple abstraction from implementation so that the two can vary independently

Answer 3

BRIDGE

Question 4

is a tree structure that contains Branches which are Folders as well as Leaf nodes which are Files

Answer 4

file system

Question 5

• The intent of this pattern is to compose objects into tree structures to represent part-whole hierarchies.
• lets clients treat individual objects and compositions of objects uniformly.
  -Compose objects into tree structures to represent part-whole hierarchies.

Answer 5

COMPOSITE

Question 6

allows to add behavior to individual objects, either statically or dynamically, without affecting the behavior of other objects from the same class.

Answer 6

DECORATOR

Question 7

is a structural design pattern that allows programs to efficiently share many objects by minimizing memory usage.

Answer 7

FLYWEIGHT

Question 8

• is a structural design pattern,it provide to create a substitute for an object, which can act as an intermediary or control access to the real object.
• The intent of this pattern is to provide a “Placeholder” for an object to control references to it.

Answer 8

PROXY

Question 9

is a class that provides a simple interface to a complex subsystem which contains lots of moving parts

Answer 9

facade
