Chapter 5 - Design & Implementation

Question 1

What are CRC Cards?

Answer 1

Class Responsibility Collaborators

Question 2

Name some Design Issues

Answer 2

responsibilities are not where they belong to / no distinction between simple and composite objects / few abstractions / long methods

Question 3

How does “Composite” work?

Answer 3

treat individual objects and compositions of objects uniformly, objects are composed into tree structure

Question 4

How does “Strategy” work?

Answer 4

define a family of algorithms, encapsulate each one, make them interchangeable

Question 5

Was is the difference btw. Strategy vs. Bridge?

Answer 5

same class diagram but strategy is meant for behavior and bridge for structure (you can use the bridge pattern approach to implement strategy pattern but not vice versa)
