Exam 8: Class and Method Design

_____ has emerged as the standard for the design of object-oriented systems.

Generalization/specialization cohesion addresses the sensibility of the inheritance hierarchy.

The constraints and contracts in class and method design models were derived from the ____________ requirements and the problem domain representations.

What is inheritance coupling? How can inheritance coupling be minimized?

Contracts document the message passing that takes place between objects.

Written documents that include explicit instructions on how to write the code to implement the method are called method specifications.

A post-condition is a constraint that must be met for a method to execute.

A For statement simply performs some action.

Method specifications can be somewhat vague, as the programmers will have a good idea of what the analyst needs done in the system.

What is Generalization/Specialization cohesion?

Subclasses inherit the appropriate attributes and methods from the superclass above them.

What is connascence? Is this desirable or undesirable in a system? Why?

Polymorphism is the mechanism that combines the processes and data into a single object.

The basic building block of a system is the _____.

Why is it necessary for an analyst to detail the specifications for the individual classes and methods? What techniques are useful for doing this documentation?

A post-condition is one that must be valid for a method to execute.

A method that performs multiple functions that are unrelated to one another exhibits Coincidental cohesion, and this type of cohesion is undesirable.

C++ forces programmers to write code with good levels of interaction coupling.

In order to verifying and validating class and method design, all constraints, contracts, and method specifications must be tested.

What is interaction coupling? How can interaction coupling be minimized?
