For all developers who want to create good code and good design.
Introduction to Object-Oriented Programming

Introduction to Object-Oriented Programming

Who would benefit from this introductory course on "object-oriented" programming? This course is for any developer who wants to write flexible code, enabling good code and good design .

All code changes. Over time, features are added, changed, and removed based on user needs. Therefore, code must be easily mutable. If change is difficult, it becomes difficult to adapt to new changes. Therefore, one of the most important skills a developer must possess is writing code with a flexible structure that can be easily modified. There are several ways to create code that is resilient to change, one of which is using object-oriented programming.

This course introduces encapsulation and polymorphism/abstraction for object-oriented programming and explores how they help create flexible and changeable code. Learn about objects, encapsulation, polymorphism, abstraction, composition, separation of functions and responsibilities, dependencies and dependency injection, and Dependency Integrity (DIP) step by step to create flexible and robust code.

This lecture
I have this goal

• Understand the encapsulation and abstraction required for object-oriented programming and learn how to use them to write code that is flexible to change.
• Learn how to split functionality and understand DI to manage dependencies.

In this lecture
You can learn things like this

• object
• Encapsulation
• Polymorphism and Abstraction
• Assembly rather than inheritance
• Separation of functions and responsibilities
• Dependency and DI
• DIP
