Study Notes

Object-Oriented Approach Advantages

A major advantage of the Object-Oriented Approach is the creation of modular, maintainable, and extensible code.

Data Treatment in Object-Oriented Programming

In Object-Oriented Programming, data is treated as an integral part of an object.

Focus of the Object-Oriented Approach

The Object-Oriented Approach focuses on data abstraction, encapsulation, and inheritance to create modular, maintainable, and extensible code.

Adding New Data and Functions

The Object-Oriented Approach allows the addition of new data and functions through inheritance and polymorphism.

Classes in Object-Oriented Programming

A class in object-oriented programming is a blueprint or template that defines the properties and behaviors of an object.

Objects in Object-Oriented Programming

Objects in object-oriented programming are instances of a class, and they have their own set of attributes and methods.

Function of Classes

The function of classes in object-oriented programming is to define the properties and behaviors of objects.

OOP Inheritance Principle

The main benefit of utilizing the OOP inheritance principle is code reusability and a more hierarchical organization of code.

Encapsulation and Abstraction

Utilizing encapsulation and abstraction contributes to hiding complex implementation details and showing only the necessary information to the user when dealing with intricate code.

Access Keywords

The 'Public' access keyword allows access to the class member from any other class.
The 'Protected' access keyword allows access to the class member from the same class and its subclasses.

Methods

Methods in the context of classes and objects perform specific actions on objects.

Attributes

An attribute in the context of classes and objects is a characteristic or property of an object.

Class Representation

A class represents a real-world entity or concept, and it defines the properties and behaviors of objects.

Creating Multiple Objects

You can create multiple objects for a class because a class is a blueprint or template that can be instantiated multiple times.
