All of the examples of 'bad code' that you showed were like my own code, so I laughed a little... Actually, I thought I knew what good code was and how to write it, but when I actually followed the examples, I realized that I actually didn't know anything at all. Thank you so much for the great lecture.

I could feel that what I thought I knew about object-oriented programming was just a presumption. Also, the fact that you explained it in detail with real-life examples helped me understand why these concepts are necessary. Thank you!!

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.

Learning programming
Everyone
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
📢 To take this course smoothly,
- A basic understanding of classes, inheritance, and interfaces in a programming language is required.
Expected questions
Q&A
Q. What programming language do you use in your classes?
The code in this lecture is written in Java. However, even those familiar with other languages like Kotlin, C#, Scala, or Python will find it quite easy to follow.
Q. What level of prerequisite knowledge is required to take the course?
You should know the following to successfully complete the course:
- What is private and public
- Differences between classes, abstract classes, and interfaces
- How to inherit
- How to override

100% enrolledIt was really helpful. I was able to understand the development intentions of senior developers at the company better, and accordingly, I think I can develop more systematically and flexibly when I develop on my own. It was a moment when I felt ashamed of the codes I had created so far. Thank you for the great lecture..ㅠㅠ
