Exam 8: Class and Method Design

When a calling method passes a variable to the called method, the two exhibit content or pathological coupling.

The signature of a method is completely specified by the name of the method and the parameters that must be passed to the method.

A Case statement is an advanced form of an If statement.

Briefly discuss the procedure for verifying and validating class and method design.

There are only two different types of constraints typically captured in object-oriented design: preconditions and postconditions.

Essentially, all OCL expressions are simply a declarative statement that evaluates to either being true or false.

A self-contained, encapsulated piece of software that can be plugged into a system is often referred to as a design a pattern.

Fan-out refers to _____.

What is method cohesion?

In an object-oriented system, changes can take place at the following level of abstraction.

Which of the following types of interaction coupling is "best?"

Method cohesion is concerned with the level of cohesion among the attributes and methods of a class.

A pre-condition is a constraint that must be met after the method executes.

Constraints can be written in either a natural language, a semiformal language, or a formal language such as ________________.

It is impossible for a subclass to inherit from more than one superclass.

What is the Object Constraint Language? Give an OCL example.

Pseudocode is useful for writing algorithm specifications.

You should try to maximize the cohesion within an encapsulation boundary and minimize the coupling between the encapsulation boundaries.

Object-oriented systems have three general types of cohesion: _____, _____, and _____.

Mixed-role class cohesion is the worst type of class cohesion.
