That guy is really good at writing code.
How do you write code like that? 🤔

There are times when I look at someone's code and think, 'Wow, that's well-written.'
When we say that the code is well written, it is actually in the same context as feeling that the code is well readable.

Ultimately, the key to code is whether it can be written in a readable way for others to see .
Beyond simply writing good code style, the key is the ability to design a structure that makes it easy for readers to read!

I've heard of the clean code principle.
I don't really understand what you're saying or why you should follow it. 🧐

Clean code is a term popularized by Robert C. Martin in his book of the same name.
It contains several guidelines that increase the maintainability of code, facilitate collaboration, and help developers write better code.

However, I have seen many cases where these guidelines remain as rules that are blindly followed without a deep understanding of them.
In this lecture , we will introduce the basic concept of 'abstraction' to make the clean code principle our own , and then introduce the mindset for writing good code one by one.

I learned the concept of object-oriented programming
So how do I apply it? 😵‍💫

Encapsulation, abstraction, inheritance, polymorphism, and SOLID principles.
Did you just memorize object-oriented concepts to prepare for the interview?

Concepts accepted only in theory are difficult to immediately manifest at the code level.
In this lecture, we will show you step by step how to understand and apply the object-oriented paradigm at the code level while refactoring complex and messy code little by little.

In this lecture 📖

A mindset for writing readable code

This is not a lecture that simply lists clean code principles and introduces guidelines such as "Do this" and "Do not do this." Rather, it explains the principles based on understanding so that the person writing the code can actively think and apply them.

A taste of the object-oriented paradigm at the code level

From [Approaches to designing objects, SOLID principles] to how to use [Value Objects, first-class collections, Enums, polymorphism], etc.
We will take a detailed look at object orientation, which we have only known in theory so far, at the code level.

Experience refactoring messy code into better code

We provide two example projects written in pure Java.
It provides practical refactoring experience by refactoring messy codes into better codes one by one.

Organize keywords that remain in your head

Since this is a lecture where the flow from the first section to the last section is important, we provide keyword-based content organization by section.
This is not a lecture that you just listen to and forget, but a lecture that stays in your head and is internalized.

Detailed explanations, charts, and example projects that you can follow along and understand.

We present key points and several illustrations for each topic to help with understanding, and after explaining the concepts, we proceed with coding through an example project.
It is structured so that you can increase your understanding by following the code from beginning to end and refactoring it yourself.

Q&A 💬

Q. Is player knowledge required?

Since this course is taught in pure Java, you only need to be familiar with basic Java grammar.
Grammar of Java 11 or higher is sufficient, and it would be good to learn together even if you come across content you don't know well. 🙂

Q. I’m curious about the practical environment!

In order to show you how to develop in practice as closely as possible, we use the IntelliJ Ultimate license by default.
I'm using macOS, but I applied the IntelliJ shortcut plugin for reference for those using other operating systems.
Please refer to the published lecture for more details. :)

Q. Can I take any section I want first, regardless of the order?

This lecture shows you code that gradually develops within one large flow, and since the later content builds on the previous content, I recommend learning sequentially from the first lecture. :)

24/01/09 It was tough.
I can't tell you how lucky I am to be able to take such a great lecture. I didn't know where to start or how to study, but I'm so grateful that I was able to organize everything through the lecture. I felt that not a single lecture was recorded carelessly, and that this lecture was made with sincerity. I want to take and learn more lectures in the future. I hope you will continue to record many good lectures. Thank you!!!!

This lecture really scratched my itch when it came to testing. Since I was studying alone and had no place to get feedback on test code, I was looking through several project repos from IT clubs or educational programs and was worried about how to write test code. This lecture was really helpful. Now that I have some idea of the direction and method, I just need to learn it myself and make it my own. Thank you for the great lecture. I could feel that you put a lot of thought into preparing the lecture. Thank you.

I always had a lot of concerns about testing while writing production code, but I learned it really enjoyably because it was explained easily with code. I think it is a great lecture that provides excellent absorption that even those who know nothing about testing can understand! Thank you for the great lecture😊😊

Of all the lectures I took in 2023, this was the most helpful and recommended lecture to those around me . In many spring lectures, they talked about the importance of test code and only used a rough assertThat, but this lecture contained only the content I wanted, such as various tools and how to use them.

★ ☆ ★ A lecture that you have to leave a review for! ★☆★ I always feared tests and felt they were difficult, so I didn't write one. However, now I know that tests are not that difficult and scary. I hope that others can take this lecture and overcome their fear of tests. Woobin's lectures are easy to focus on and easy to understand. I wonder if you are planning other lectures. Thank you.

No matter how hard I searched, I had a hard time finding a basic lecture on why Test Code should be written, its definition, necessity, and how to apply it in practice. I think this is where my search ended up.
This lecture is so basic and practical, and I think it is the best lecture I have ever taken, out of all the expensive and trendy lectures.
thank you
