Object Oriented Paradigm

Question 1

A class defines the set of shared _________ and _________ found in each object within that class.

Answer 1

Attributes, behaviors.

Question 2

In a single unit called an object, what two things are combined?

Answer 2

Data, and the functions that operate on that data.

Question 3

Classes, like humans, can have characteristics and __________?

Answer 3

Behaviors

Question 4

This is more detailed instance of a class…

Answer 4

Object. ex. Class = Student; Object = David.

Question 5

What term is used when an object is created from a class?

Answer 5

Instantiation.

Question 6

APIE stands for what?

Answer 6

Abstraction, Encapsulation, Inheritance, Polymorphism.

Question 7

Abstraction means what?

Answer 7

Abstract up to only the features, properties or functions that are relevant.

Question 8

_________ dictates what should and should not be abstracted.

Answer 8

Context.

Question 9

What is encapsulation?

Answer 9

The act of grouping into a single object both data and the operations that affect that data.

Question 10

What is required to be for a method that wants to access data stored within an object?

Answer 10

That method needs to be defined by that object’s class.

Question 11

What are two reasons as to why encap is significant?

Answer 11

Reliable objects that have total control over their attributes.

Only the objects change attribute values, so a potential issue is contained.

Question 12

Inheritance is what?

Answer 12

The process of creating new classes from base classes.

Question 13

What is a derived class and a base class

Answer 13

Derived = Used a previous (Base Class) as a template.

Question 14

True or False. The derived class is limited to the attributes and behaviors of the parent/base class.

Answer 14

False, the derived class can ADD attributes and behaviors.

Question 15

What is polymorphism?

Answer 15

Being able to perform the same operation on different objects. EX. telling a bird to move. Some fly, some run, some swim.

Question 16

An object is to a class, what a variable is to a ________.

Answer 16

Data type.

Question 17

An object is said to be what towards a class?

Answer 17

An instance.

Question 18

What are methods?

Answer 18

Member functions that are included within a class in order to implement a specific behavior that objects of that class are capable of performing.

Question 19

How is extensibility similar to a derived class?

Answer 19

Extensibility refers to creating new DATA TYPES from existing ones, where derived classes are created from existing base classes.

Question 20

What is information hiding?

Answer 20

Information hiding is the technique of concealing implementation details within the objects themselves, while the interface remains visible.

Question 21

A system of objects is defined as:

Answer 21

Two or more interacting or interrelated, non-nested objects.
