More Java, different ways to manipulate code

In fact, there were many cases where I didn't clearly understand the concepts of Spring DI, AOP, IOC, etc. or the structure of the JVM when I read various blog posts. Since I didn't understand the principles of the technologies, I naturally just memorized the technologies, and even that would be forgotten over time and I would wonder, "What was it?" I happened to watch this lecture while preparing for a job change, and since I was able to understand the principles of the technologies that I had been using without thinking, I felt like I understood them a little more clearly. If I listen to the same lecture a few more times, I think I will think more deeply and understand more deeply whatever I read. Also, although it is knowledge that may disappear due to volatility, I think it is different from knowing the principle of whether something works or not, so it was a really meaningful lecture for me.

I was going to leave it alone, but it's been useful and fun since episode 1. I give it full marks!

The lecture is so interesting. After listening to this lecture, I like Baek Gi-seon 100 times more, so I will call him Man (Baek * 100) Gi-seon.

I think this is a must-have course for Java developers.

I was always amazed by Spring's DI, AOP, and Lombok technologies, but I didn't understand exactly how they worked. I understood a lot through this lecture. The lecture wasn't too long, so I think it was easy to concentrate.

This is a really good lecture for developers who use Java for object-oriented programming. Those who have studied or used not only the basic grammar of Java but also Spring AOP can take this course in a smooth manner. I've always wondered how annotation processors work, so this is a good lecture that will allow me to Google the basic concepts and general knowledge. I recommend that you don't just follow along from the beginning, but just listen once and practice the second time.

Advanced Java skills that are not covered well in most Korean courses. Highly recommended for developers who like Java and Kotlin!! By the way, I haven't seen Kiseon on YouTube lately.. I want to see him. from. Naver Junior

While studying Lombok and annotation processors, I remembered a lecture I had purchased a while ago and listened to it diligently..! Up until now, I only had knowledge equivalent to a Java basics book, so while listening to the lecture, I felt like I had traveled to a completely different world.. Should I say it was like a dream...!! I may not be able to delve deeper and study right away, but just knowing these principles will change my perspective on the Java world a little. Thank you. I hope to see more good lectures in the future.
