A class has an attribute in which a range of values has a semantic meaning. This class has _____ connascence.

What are the four opportunities for reuse identified in the text?

Invariants are a type of constraints captured in object-oriented design

Like other problem domain models, the _____________, contracts, and method specifications in class and method design need to be verified and validated.

Dynamic binding refers to the ability of object-oriented systems to defer the data typing of objects to run time.

In terms of levels of abstraction, which of the following is at the lowest level relative to the rest?

When a method of one object refers to the inside hidden parts of another object, these methods are exhibiting _____ coupling.

What is class cohesion?

A method that combines two functions that use the same attributes to execute exhibits Communicational cohesion.

Coincidental is the worst type of method cohesion.

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

A Case statement in Structured English has several mutually exclusive branches.

A class/object should only represent one thing, and a method should only solve a single task. This principle is often referred to as _____.

Use Structured English or pseudocode to write the logic for the process "register for a class" at your college or university. Focus on a single class, but consider the possible exceptions that may occur when you try to register for that class.

A derived attribute results from storing the value of a computation.

Constraints can only be written in either a semiformal language or a formal language.

Contracts contain a detailed algorithmic description of how the method is to work.
