Get off work fast, keep your code clean, start refactoring using IntelliJ (with shortcut keys) - Basics

I recommend this to these people.

• A developer with 2nd or 3rd year of experience who is just starting Java development
• Developers who have heard the term refactoring but are unsure of how to apply it
• Developers who have learned refactoring techniques from books but do not know how to connect these techniques to effectively modify code.

Students' Concerns & Solutions

• When you have a lot of code to fix, and it's so complex that you don't know where to start...
• I've heard of the simple refactoring technique in the IDEA editor, but I don't know how it works...
• If you look at how each refactoring technique explained in this lecture works and follow the practical steps, your worries will be solved!!!!

What you'll learn in this lecture ✨

If you want to quickly, safely, and easily fix the Java code you're currently writing, you absolutely must know the refactoring techniques below!

• Introduce Variable ( Exclude as a variable )
• Extract Method ( Extract by method )
• Change Signature ( Change the method )
• Extract Delegate ( Extract as object )
• Introduce Parameter Object ( make parameters immutable objects )
• Move Instance Method ( and move the method )
• Replace Inheritance With Delegate ( Learn how to break inheritance relationships )

In this lecture, you will learn each of the refactoring techniques mentioned above.

Through hands-on exercises, we'll teach you how to use each refactoring technique to safely and quickly modify your code.

What you'll learn 📚

Experience the evolution of your code through refactoring. !!!!!

Have you ever tried modifying an endless if statement like the one below?

Using the refactor feature supported by IntelliJ IDEA, you can evolve it as follows with just a few modifications:

Expected Questions Q&A 💬

Q. Why should I learn IntelliJ IDEA's refactor feature?
A. When modifying code, there are many cases where a simple "find and replace" operation isn't enough. Therefore, each Java editor provides a refactoring function, though it may have a different name. Mastering refactoring techniques can significantly reduce the difficulty of modifying code, so I believe it's essential to learn them.

Q. Can non-majors also take the course?
A. Yes, if you have some basic development knowledge, it's possible . If you have a passion for development, I don't think your major matters. :) However, having some basic development experience can be helpful. If you find it difficult, don't hesitate to ask. :)

Q. Is this course platform-specific?
A. Yes, this course covers features supported by IntelliJ IDEA, a popular Java editor used by many major companies. Since the course is designed for MacOS, it may be platform-specific. However, for Windows users, shortcuts are displayed on the recorded screen, so you should be able to follow along without any issues.
