Learning design patterns is like learning techniques in Jiu-Jitsu.

You've probably seen self-defense or Jiu-Jitsu technique demonstration videos on YouTube.

By carefully observing Jiu-Jitsu content, you can learn how to subdue an opponent or defensa yourself by leveraging various aspects of the human body, like joints, the principle of leverage, and the center of gravity. Watching these techniques, which utilize the structure and mechanics of the body, you might think, "I've used my body all my life, but I never realized it could do this."

While not as intricate as the human body, object-oriented programming languages provide complex features beyond simply using classes and objects. Concepts like inheritance, polymorphism, and encapsulation are often challenging to apply effectively in practice. As a result, many people end up using object-oriented languages, like Java, in a procedural manner, simply because they don't know how to make full use of these features.

By learning object-oriented design patterns, you'll discover how to utilize the complex features of object-oriented languages effectively in real-world scenarios. Design patterns offer ways to solve complex problems more easily and make coding and maintenance much simpler. Just as learning techniques in Jiu-Jitsu enables you to use them as needed, learning design patterns helps you apply object-oriented features more effectively in practical situations.

Who Should Take This Course?

1. Those Who Want to Use Object-Oriented Languages Effectively

Many people learn concepts like classes, abstraction, inheritance, and interfaces, yet are unsure how these can be applied in real-world situations. Through over 50 examples, this course will show you how to write elegant and diverse code using object-oriented features, helping you grasp their practical applications.


2. Those Who Want to Write 'Better' Code in Practice

If you're aiming to write code that's not only functional but also easy for others to understand and modify, this course is for you. Learning design patterns will make your code cleaner and easier to maintain or extend, saving time in the long run. It will help you work more efficiently in a professional environment.

After Completing This Course, You Will Be Able To:

  • Understand the fundamental concepts and design principles of object-oriented programming and apply them in real-world scenarios.

  • Learn various design patterns and gain specific methods for applying them in practical situations.

  • Develop the skills to write maintainable and reusable code structures.

  • Master systematic and efficient approaches to solving complex software challenges.

  • Maintain code consistency, leading to smoother collaboration with team members and faster development speed.

What You'll Learn

Object-Oriented Design Principles

We'll start by exploring what object-oriented programming (OOP) is and why it was created, followed by a brief, simple overview of its core components. Through the foundational SOLID principles, you'll learn what it takes to design robust yet flexible software—laying the groundwork for understanding design patterns.

25デザインパターン

Dive into the 25 most widely-used design patterns, each explained with two Java examples. You'll learn 5 creational patterns, 7 structural patterns, and 13 behavioral patterns, equipping you with practical solutions for tackling various design challenges you'll encounter in real-world applications.

Frequently Asked Questions

Q. What programming language knowledge is required for this course?

The examples in this course are written in Java. Anyone with a basic understanding of Java or similar languages like C# or Kotlin should be able to follow along without difficulty. For those who are familiar with other types of languages, the examples are kept simple without relying on Java's advanced features to make the course accessible.

Q. How in-depth is the content covered?

This course is designed to help you understand 25 design patterns quickly and easily. The focus is on intuitively explaining the principles and demonstrating how each pattern is implemented through two examples.

For those looking for a more theoretical approach or advanced practical applications in real-world projects, this course may feel less comprehensive. Please watch the five free pattern videos available before enrolling to ensure it matches your learning goals.
