What you will gain after the course

Kotlin, Kotlin Basic Grammar
Practical Java + Spring Project -> Kotlin + Spring Project Conversion Practice
Practical code, tips for coding more like Kotlin
Various testing methods such as Kotlin Junit5, Mockk, Kotest

If I learn Kotlin, can I use it in my work right away? 🤷

Even if you learn Kotlin grammar, it is difficult to use it in practice. I don't want to modify existing projects incorrectly... Should I convert all existing Java codes at once? Is there no safe way?
ㅤ

🏹 If you take this course,

You can learn in detail about Kotlin's latest grammar for 2024.
You can safely convert a practical Java project (using lombok) into a Java+Kotlin project.
- I know and can use scripts, plugins, and libraries for mixed Java+Kotlin+Spring builds.
You can learn and utilize Kotlin-like coding.
You can write more fun and useful tests using Kotlin-specific tests MockK and Kotest.

ㅤ

📚 Detailed lecture notes are provided.

 class TargetUser (
   var toDevelopers = "Those who have experience with Java + Spring in practice"
   var forDevelopers = "Those who want to learn Kotlin and apply it in practice"

   //Recommended for those who want to learn it in advance even if they don't plan on using it right away!
 )

📌 Can I immediately apply a new language in my work by only learning its grammar? 🤔 📌 You also need to understand the ecosystem (build scripts, libraries) for building the language.

📌 Java to Kotlin teaches you two things: reviewing basic Kotlin grammar and learning various know-hows needed to use Kotlin in real-life situations.

📌 How to modify/write a Gradle build script to build Java, Kotlin, and lombok together

📌 Detailed description of various plugins/libraries for using Kotlin in Spring

When I first started working on a Kotlin project, I always wondered what Kotlin-like was, but after taking this lecture, I realized that I was still in the Java style. I used to follow what other people wrote for kotest, but I think I learned more, so it was good. I'm looking forward to the next lecture. Thank you!
- seyolInstructor
  Thank you for the course review, Shingiru. 🥰 Even if you change the grammar to Kotlin, if you code the same way as Java, there are many parts where the advantages are diluted. If you make good use of Kotlin's features, you can get the most out of the advantages. I'm so happy that my lecture was helpful. ☺️ I'm preparing an introductory course on functional programming in Kotlin this fall, and I think it will be of great help to those who are working on a Kotlin project. Please look forward to it~^^

I'm planning to convert a project that I've been using Java for 6 years to Kotlin. I liked the lecture that organized the Kotlin plugin, and I wanted to apply it quickly while watching the process of changing it to Kotlin-like code that can be used in practice. It would be good to apply kotest as well! I'm also looking forward to the Kotlin functional programming lecture. It was very helpful👍👍
- seyolInstructor
  Thank you for the course review, Riverway. 😆 When I first switched from Java to Kotlin, the most difficult part was understanding the surrounding ecosystem, such as plugins, rather than the grammar, so I put a lot of effort into making this course. Thank you for checking it out. Please definitely utilize Kotlin-like code and fun test codes made with kotest. As a side note, you can quickly create boilerplate codes for test codes with GPT or Copilot. However, the quality varies, so I recommend that you learn the course content before using it. ㅎ I'm working hard on the functional programming course right now~! I'll work hard on it in the summer and provide it by fall. Thank you for your anticipation😊

I've been using Kotlin a lot in the backend lately, so I really wanted to learn it. The Kotlin grammar was a bit awkward and difficult, but the instructor explained it easily :) I'm trying to convert existing Java code to Kotlin, so I think it will be a great help. I'm looking forward to other lectures. Thank you :)
- seyolInstructor
  Thank you so much for your first class review, lovelove🙏 I only used Java, so I felt awkward when I first used Kotlinㅎㅎ I hope you can successfully convert your existing project!! If there is anything that doesn't work well during the conversion, feel free to leave a question anytime~! I'm also planning a Kotlin + Spring backend course for beginners and a Kotlin functional programming course😄 Please look forward to it!🕺💃 🙇🙇‍♀️ Happy New Year
