Q61.
What is the formal viewpoint of an object?

a.

An abstraction of something in a problem domain

b.

A state machine with a finite set of states and a finite set of state functions

c.

A record of data and code elements

d.

A value-based mathematical formalism

Discuss
Answer: (b).A state machine with a finite set of states and a finite set of state functions Explanation:The formal viewpoint considers an object as a state machine with a finite set of states and a finite set of state functions that map old states and inputs to new states and outputs.
Q62.
What makes formalization of the concepts and constructions of object-oriented languages difficult?

a.

Mathematical formalisms tend to be value-based

b.

Imperative concepts are easy to fit within mathematical schemes

c.

The concepts and constructions of object-oriented languages are well-defined

d.

Analysis and design are not different

Discuss
Answer: (a).Mathematical formalisms tend to be value-based Explanation:The mathematical formalisms tend to be value-based and that imperative concepts, such as state and sharing, central to object-oriented languages do not fit easily within such schemes, making the formalization of these concepts and constructions difficult.
Q63.
What is the definition of an object according to Coad and Yourdon (1991)?

a.

A state machine with a finite set of states and a finite set of state functions

b.

An abstraction of something in a problem domain, reflecting the capabilities of a system to keep information about it, interact with it, or both; an encapsulation of Attribute values and their exclusive Services.

c.

A record of data and code elements

d.

A value-based mathematical formalism

Discuss
Answer: (b).An abstraction of something in a problem domain, reflecting the capabilities of a system to keep information about it, interact with it, or both; an encapsulation of Attribute values and their exclusive Services. Explanation:The definition of an object given by Coad and Yourdon (1991) is "an abstraction of something in a problem domain, reflecting the capabilities of a system to keep information about it, interact with it, or both; an encapsulation of Attribute values and their exclusive Services."
Q64.
What is an attribute in the context of Entity--Relationship Modeling?

a.

Properties that depend on other entities.

b.

Properties whose value does not depend on other entities.

c.

Relationships between entities.

d.

None of the above.

Discuss
Answer: (b).Properties whose value does not depend on other entities. Explanation:In Entity-Relationship Modeling, attributes represent intrinsic properties of entities, properties whose value does not depend on other entities.
Q65.
In UML, how are attributes and relationships modeled?

a.

Both are properties of a class.

b.

Attributes are simple properties and relationships are more complex properties.

c.

Relationships are properties of a class and attributes are not.

d.

Attributes are properties of a class and relationships are not.

Discuss
Answer: (a).Both are properties of a class. Explanation:In UML, the distinction between attributes and relationships formally does not exist. Both are properties of a class.
Q66.
What does the term attribute refer to in the context of object-oriented modeling?

a.

Any field in the underlying data structure.

b.

Structural attributes of an object.

c.

Behavioral attributes of an object.

d.

None of the above.

Discuss
Answer: (a).Any field in the underlying data structure. Explanation:In the context of object-oriented modeling, the term attribute is sometimes used to denote any field in the underlying data structure.
Q67.
What constitutes the state of an object in object-oriented modeling?

a.

The intrinsic properties represented as values.

b.

The mutual properties represented as references to other objects.

c.

Both intrinsic and mutual properties represented as values or references.

d.

None of the above.

Discuss
Answer: (c).Both intrinsic and mutual properties represented as values or references. Explanation:Collectively, the set of attributes of an object constitutes its state. It includes the intrinsic properties represented as values and the mutual properties represented as references to other objects.
Q68.
What do individual objects of a class in a programming language called?

a.

Instance

b.

Class

c.

Attributes

d.

Services

Discuss
Answer: (a).Instance Explanation:Individual objects of a class in a programming language are called instances of that class.
Q69.
What do objects in a programming language encapsulate?

a.

State

b.

Behaviour

c.

Both state and behaviour

d.

None of the above

Discuss
Answer: (c).Both state and behaviour Explanation:Objects in a programming language encapsulate both state and behaviour, i.e. the way in which it acts upon other objects and is acted upon by other objects.
Q70.
What is the major behavioral aspect of an object?

a.

State change

b.

Service provided

c.

Client-server view

d.

Contract

Discuss
Answer: (a).State change Explanation:The major behavioral aspect of an object concerns state changes.
