Learn 25 Design Patterns from Yalco, a YouTuber with 100K Subscribers

Learning design patterns is like learning jiu-jitsu techniques.

You've probably seen videos on YouTube demonstrating self-defense techniques or jiu-jitsu moves.

If you carefully watch jiu-jitsu related content, you can learn various methods to subdue opponents or defend yourself by utilizing the body's joints, leverage principles, center of gravity, and other characteristics. Seeing various techniques that utilize the structure and mechanics of the human body, you realize, 'I've been using it my whole life, but I can do these kinds of things with my own body.'


While not as complex as our bodies, object-oriented programming languages provide sophisticated features that go far beyond simply using classes and objects. Even when learning concepts like inheritance, polymorphism, and encapsulation, it's difficult to figure out on your own how to use them effectively in real-world practice. As a result, many people who have learned object-oriented languages like Java don't know how to utilize these features properly and end up using them essentially like procedural languages.

By learning object-oriented design patterns, you'll understand how to effectively use the complex features of object-oriented languages in real-world practice. Through various design patterns, you can learn methods to solve complex problems more easily and make creating or modifying programs more convenient. Just like learning techniques in jiu-jitsu and applying them according to the situation, learning design patterns helps you utilize the features of object-oriented languages more effectively in actual scenarios.

Who would benefit from taking this course?

1. Those who want to properly use object-oriented languages

Many of you have learned concepts like classes, abstraction, inheritance, and interfaces, but may not know how these can be specifically utilized in real-world practice. Through over 50 examples, you'll be able to see in this course how beautifully and diversely you can write code using object-oriented features.


2. Those who want to write 'better' code in practice

If you want to write 'good' code that is not just functional, but also easy for others to understand and modify, this course is suitable for you. Learning design patterns will make your code cleaner and easier to maintain and extend later, saving you time. It will help you work more efficiently at your workplace.

After taking the course

  • You will understand the basic concepts and design principles of object-oriented programming and be able to apply them in practical work.

  • You will learn various design patterns and acquire specific methods on how to utilize them in real-world applications.

  • You will develop the ability to write code with a structure that is easy to maintain and reusable.

  • You will learn how to solve complex software problems systematically and efficiently.

  • Maintaining code consistency makes collaboration with team members smoother and also speeds up development.

What makes Yalco's lectures different?

Easy explanations through analogies and visual elements

Yalco, the explanation master who makes even the most difficult concepts easy to understand! With years of accumulated expertise, I'll help you grasp all patterns at once. Without complex explanations or class diagrams, you can easily learn patterns through intuitive graphics and perfect examples.

Clean and visually engaging videos

We provide a highly readable learning experience through subtitles and code highlighting applied to all videos, while progressing quickly through the content without unnecessary processes like code typing. You can learn from object-oriented concepts to 25 patterns in a compressed 3-hour lecture.

You'll learn this kind of content

Object-Oriented Design Principles

We'll explore what object-oriented programming is and why it was conceived, then examine its constituent elements one by one in a simple and easy-to-understand manner. Through the SOLID principles that form the foundation of design patterns, you'll learn what kind of design creates robust and flexible software.

25 Design Patterns

Learn about the 25 most widely used design patterns, each with two Java examples. Study 5 creational patterns, 7 structural patterns, and 13 behavioral patterns to learn how to effectively solve various design problems you'll encounter in practice.

Learning Patterns

  • Facade Pattern

  • Strategy Pattern

  • Template Method Pattern

  • Singleton

  • State Pattern

  • Adapter Pattern

  • Bridge Pattern

  • Factory Method Pattern

  • Proxy Pattern

  • Observer Pattern

  • Flyweight Pattern

  • Abstract Factory Pattern

  • Mediator Pattern

  • Visitor Pattern

  • Builder Pattern

  • Decorator Pattern

  • Command Pattern

  • Memento Pattern

  • Prototype Pattern

  • Chain of Responsibility Pattern

Do you have any questions?

Q. What programming languages and to what extent do I need to know them to take this course?

The examples in the lectures are written in Java. Those who have learned Java or similar languages like C# or Kotlin beyond the basic level can take this course without difficulty.

I have created examples without using Java's advanced features as much as possible, so that those who have learned languages from different families can take the course without major difficulties.

If you feel that your knowledge of Java is lacking, you can learn sufficient content from the free part of Yalco's Properly Understanding Java. (The free content includes up to the object-oriented programming section.)

Q. How in-depth is the content covered?

This course aims to help you understand 25 patterns as easily and quickly as possible. It focuses on intuitively explaining what principle each pattern represents and how it can be implemented through 2 examples.

Those seeking theoretically in-depth content or detailed practical applications may find it insufficient. Therefore, please be sure to check the 5 pattern videos provided as free previews before enrollment.

    많은 고민을 하고 강의를 제작했다는게 느껴지는 강의였습니다. 각각 강의 시간은 짧은게 전혀 단점이 아닐 정도로 핵심은 모두 담겨있으며, 이해가 쉽도록 배려해주신 훌륭한 강의였습니다. 이 가격에 이정도 퀄리티를 접해보니 앞으로 눈이 높아져서 다른 강의들 함부로 못 볼 것 같네요. ps. 개인적으로 구연산 팬입니다.. 항마력 높이시고 다시 뵙길 고대합니다. 감사합니다.
