Oop

Front 1

The two components of an object

Back 1

Properties (data) & Methods (programs). The Programs & the Data they operate on are bundled into one entity: the object.

Front 2

What an object would look like if we had one.

Back 2

Class

Front 3

Making an object of a given class. Cookie cutter => Cookie

Back 3

Instantiation

Front 4

Attempts to use the classifications, relationships, & properites of an object in the system to aid in proram development & code re-use

Back 4

Object Oriented Programming

Front 5

Can be almost any item or concept

Back 5

Object

Front 6

OO software utilizes both [_____] & [_____] that interact to meet your needs

Back 6

1. attributes
2. operations

Front 7

Properties or Variables that relate to the object.

Back 7

Attributes

Front 8

Methods, actions, or function that the object can perform to modify itself or perform for some effect.

Back 8

Operations

Front 9

Encapsulation is also known as ...

Back 9

data hiding

Front 10

Data hiding is also known as ...

Back 10

Encapsulation

Front 11

Access to the data within an object is available only via the object's operation, known as the interface.

Back 11

Encapsulation

Front 12

Unique & identifiable collection of stored data & operations that operate on that data. Separate variables act as handles (unique identifiers) for the object.

Back 12

Object

Front 13

Represent a set of objects that might vary individually, but have a certain amount in common.

Back 13

Class

Front 14

Contains objects that all have the same operations behaving the same way & the same attributes representing the same things, although the value of those attributes vary from object to object.

Back 14

Class

Front 15

Different classes can have different behaviors for the same operation (Cars & Bikes both "move" but don't get confused). [The verb "move" can be associated with a particular set of actions only after the object acted on is made known.]

Back 15

Polymorphism

Front 16

This allows you to create a hierarchical relationship between classes using "subclasses."

Back 16

Inheritance

Front 17

This inherits attributes and operations from its superclass.

Back 17

Subclass

Front 18

Subclass is also known as...

Back 18

Derived class, Child

Front 19

Derived class is also known as...

Back 19

Subclass

Front 20

Superclass is also known as...

Back 20

Parent

Front 21

Parent class is also known as...

Back 21

Superclass

Front 22

These are created by declaring variables within a class definition using keys that match their visibility: public, private, or protected.

Back 22

Attributes

Front 23

Three kinds of visibility for an attribute:

Back 23

Public, Private, and Protected.

Front 24

Created by declaring functions within the class definitions.

Back 24

Operations

Front 25

This is called when an object is created, and it also normally performs useful initialization tasks such as setting attributes to sensible starting values or creating other objects needed by this object.

Back 25

Constructor

Front 26

Allow for some functionality that will be executed just before a class is destroyed, which happens when all references to class have been unset or fallen out of scope.

Back 26

Destructors

Front 27

Two steps for instantiating classes

Back 27

1. declare a class
2. create an object

Front 28

How to create an object in three steps:

Back 28

1. use the "new" keyword
2. specify what class your object will be an instance of
3. provide any parameters required by the constructor.
