Question 1

____ are the characteristics that define an object.&#10;A) Instances&#10;B) Attributes&#10;C) Behaviors&#10;D) Methods

Accepted Answer

Attributes are the characteristics that define an object, such as its color, size, and shape. Instances refer to the specific occurrence of an object, behaviors refer to the actions an object can take, and methods are the functions or procedures that can be applied to an object.

Question 2

Object-oriented programmers sometimes say an object is one ____ of a class.&#10;A) enumeration&#10;B) instantiation&#10;C) member&#10;D) reference

Accepted Answer

An object is created by instantiating a class, which means creating a specific instance of that class. The other options are not accurate descriptions of what an object is in relation to a class.

Question 3

Instance variables are often called ____ to help distinguish them from other variables you might use.&#10;A) rows&#10;B) records&#10;C) columns&#10;D) fields

Accepted Answer

Instance variables are commonly referred to as fields in programming terminology. Rows and columns refer to the structure of data in a table, while records are a collection of fields or values. Therefore, option D is the best choice to describe instance variables.

Question 4

Methods in a class are static instance methods by default.

Accepted Answer

Methods in a class can be either static or instance methods. By default, a method is an instance method and requires an instance of the class to be called. To make a method static, the keyword "static" needs to be added to the method signature.

Question 5

The concept of a class is useful because of its ____.&#10;A) reusability&#10;B) mapping to reality&#10;C) abstract nature&#10;D) portability

Accepted Answer

Classes allow for code to be reused in multiple parts of a program, increasing efficiency and reducing redundancy.

Question 6

The data components of a class that belong to every instantiated object are the class's ____.&#10;A) numeric variables&#10;B) string variables&#10;C) instance variables&#10;D) data variables

Accepted Answer

Instance variables are data components of a class that belong to every instantiated object. Numeric and string variables are types of data that can be stored in instance variables but do not describe the characteristics of the instance variables themselves. "Data variables" is not a commonly used term in object-oriented programming.

Question 7

The accessor method is another name for the set method.

Accepted Answer

The accessor method (also known as getter method) retrieves the value of an attribute, whereas the set method (also known as mutator method) sets or updates the value of an attribute. They are two separate methods with different purposes.

Question 8

Declaring a class does not create actual objects.

Accepted Answer

Declaring a class only defines a blueprint or a template for creating objects. The actual objects are created by instantiating the class using the `new` keyword.

Question 9

____ is a programming model that focuses on an application's components and data and the methods you need to manipulate them.&#10;A) Classical programming&#10;B) Functional programming&#10;C) Procedural programming&#10;D) Object-oriented programming

Accepted Answer

Object-oriented programming focuses on creating and manipulating objects, which combine data and the methods needed to manipulate that data. It emphasizes modularity, encapsulation, and inheritance, making it a popular choice for complex applications. Classical programming, functional programming, and procedural programming all have different focuses and approaches.

Question 10

Object-oriented programmers usually specify that their data fields will have private access.

Accepted Answer

This is because ensuring private access to data fields helps to maintain encapsulation and data integrity in the object-oriented program.
