Object Oriented Programming

Object

a instance of a class that contains state and behavior.

Object Oriented Programming

a methodology or paradigm using objects and classes

Class

a blueprint for creating objects, defining their properties and behaviors.

Constructor

a special method used to initialize objects when they are created.

Default Constructor

a constructor that does not take any parameters and initializes an object with default values.

Parameterized Constructor

a constructor that does take parameters and initializes an object with specific values.

Constructor Overloading

the ability of a class to have multiple constructors with different parameter lists

Inheritance

process in which the object class acquires all the properties and behaviors of the parent class

Sub-class

a class that inherits the super-class

Super-class

a class that gets inherited by the sub-class

Reusability

a technique where it will facilitate you to reuse the fields and methods of one class to create a new class

Polymorphism

ability of an object to take on different forms to respond to the same method call or operators

Method Overloading

a class that has multiple methods having the same name but with different parameters

Method Overriding

a sub-class has the same method name as declared in the parent class

Encapsulation

process of wrapping code and data together in a single unit

get()

a read-only method used to retrieve different attributes

set()

a write-only method used to modify attributes

private

a keyword only accessible within the same class

default

a keyword only accessible within the same package

protected

a keyword accessible within the same classes and subclasses of other packages

public

a keyword accessible from anywhere in your program

Abstraction

process of hiding implementation details and showing functionality to the user

Generalization

process of extracting shared characteristics of two or more classes, combining them into a generalized classes

Specialization

creating a new sub-class from an existing class

Abstract Class

a class that is declared abstract in which objects cannot be instantiated from them

Abstract Method

a method declared without any implementations
