Art1P23Q1: What is a package that has three other packages depending on it said to be?

Answer: Responsible to those three other packages.

Answer: An irresponsible package.

Art1P23Q4: What is a package that has three other packages depending on it said to be?

Answer: A dependant package.

Art1P23Q5: What is a package that is independent and responsible to other packages said to be?

Answer: A stable package.

Art1P23Q6: What is an irresponsible, dependant package said to be?

Answer: An instable package.

Art1P24Q2: What is afferent coupling?

Answer: The number of classes outside the package that depend on classes inside the package.

Art1P24Q3: What is efferent coupling?

Answer: The number of classes outside the package that classes inside the package depend on.

Art1P24Q4: What is the formula for determining the instability of a package?

Answer: Instability equals efferent coupling divided by afferent coupling plus efferent coupling.

Art1P26Q1: What is the formula for determining the abstractness of a package?

Answer: Abstractness equals the number of abstract classes in the package divided by the total number of classes.

Answer: The absolute value of the abstractness plus instability minus one.

PragC5Q1: What is the Law of Demeter?

Answer: Any method of an object should call only methods belonging to:

• itself,
• any parameters that were passed into the method,
• any object it created, or
• any directly held component objects.

PragC5Q2: What is the response set of a class?

Answer: The number of functions directly invoked by methods of the class.

Art1P21Q2: What design pattern should be used when a client type class directly depends on a server type class?

Answer: An Abstract Server.

Art1P21Q3: What is the Abstract Server design pattern and what is its advantage?

Answer: An Abstract Server is an abstract interface between a client and a server. Its advantage is that the abstract interface becomes a “hinge point” that design can flex around.

Art1P29Q1: What design pattern should be used when inserting an abstract interface is not feasible?

Answer: Adapter.

Art1P29Q2: What is the Adapter design pattern?

Answer: The Adapter is an object that implements the abstract interface to delegate to the server. Every method of the adapter simply translates and then delegates.

Answer: Make sure it isn't just a coincidence.

PragC6Q3: What is the problem with the building metaphor of software development?

Answer: Buildings are not normally refactored.

PragC6Q4: What are four reasons for refactoring?

Answer:

• Duplication (violation of the DRY principle).
• Non-orthogonal design.
• Outdated knowledge.

PragC6Q5: What are Martin Fowler's three tips on refactoring?
