Q71.
What happens when a client requests some service from a server object in a programming language?

a.

The server object fails to deliver the service.

b.

The client asks more than what is stated in the contract.

c.

The client and the server operate as intended.

d.

The client and the server violate the contract.

Discuss
Answer: (c).The client and the server operate as intended. Explanation:In order for a collection of objects to operate together as intended, each of the objects must be able to rely on the proper operation of the objects with which it interacts. When a client requests some service from a server object, the client will not ask more than what is stated in the contract, while the server promises to deliver what is stated in the contract.
Q72.
What happens to an object instance over time in a programming language?

a.

It remains static.

b.

It becomes destroyed.

c.

It changes.

d.

None of the above

Discuss
Answer: (c).It changes. Explanation:The state of an object instance is not static, but changes over time: the object instance is created, updated, and eventually destroyed.
Q73.
Can information requested from an object in a programming language only concern the state of the object instance?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (b).No Explanation:Information requested from an object in a programming language may concern the state of the object instance, but it may also involve a computation of some sort.
Q74.
What is the definition of a class in programming language?

a.

A set of attributes that an object has

b.

An individual object of a class

c.

The way in which an object acts upon other objects

d.

A collection of objects that operate together

Discuss
Answer: (a).A set of attributes that an object has Explanation:At the programming-language level, objects that have the same set of attributes are said to belong to the same class.
Q75.
What is the purpose of a contract between client and server objects?

a.

To ensure that the objects operate as intended

b.

To ensure that the client only asks what is stated in the contract

c.

To ensure that the server only delivers what is stated in the contract

d.

Both b and c

Discuss
Answer: (d).Both b and c Explanation:In order for a collection of objects to operate together as intended, each of the objects must be able to rely on the proper operation of the objects with which it interacts. The client will not ask more than what is stated in the contract, while the server promises to deliver what is stated in the contract.
Q76.
What does the major behavioral aspect of an object concern?

a.

State changes

b.

The creation of an object

c.

The destruction of an object

d.

The request of information from an object

Discuss
Answer: (a).State changes Explanation:The major behavioral aspect of an object concerns state changes. The state of an object instance is not static, but changes over time: the object instance is created, updated, and eventually destroyed.
Q77.
What is the goal during analysis and design in programming?

a.

To identify individual objects

b.

To relate the object types (classes)

c.

To identify the set of objects, their attributes and services

d.

To define the full set of attributes for each object

Discuss
Answer: (c).To identify the set of objects, their attributes and services Explanation:One of our major concerns during analysis and design is to identify this set of objects, together with their attributes (state) and services (behavior).
Q78.
What is the relationship between Furniture, Table, and Chair in programming?

a.

Furniture is a client, Table and Chair are servers

b.

Furniture is a generalization of Table and Chair

c.

Table and Chair are specializations of Furniture

d.

Furniture is an object, Table and Chair are classes

Discuss
Answer: (b).Furniture is a generalization of Table and Chair Explanation:If we have objects Table and Chair, we may also define a more general object Furniture. Table and Chair are said to be specializations of Furniture, while Furniture is a generalization of Table and Chair. These relations are also known as ‘is-a’ relations.
Q79.
What is the relation between Chair and Furniture in programming?

a.

Chair is a restriction of Furniture

b.

Furniture is a restriction of Chair

c.

Chair and Furniture are not related

d.

None of the above

Discuss
Answer: (a).Chair is a restriction of Furniture Explanation:In this view, an object is a restriction of the objects of which it is a specialization
Q80.
What is the purpose of the is-a relation in object-oriented design?

a.

To describe the relationship between a set and its members

b.

To describe the real-world part-of relationship

c.

To organize objects into a hierarchy

d.

To describe the representational part-of relationship

Discuss
Answer: (c).To organize objects into a hierarchy Explanation:The is-a relation is one way to organize (object) types into a hierarchy.
