I was always in the state of 'Will this lecture be able to hear?', but the biggest motivation for me to access the lecture even in my absent-minded state was none other than the instructor's closing comment. I received encouragement and support, and I was able to finish it with strength. In fact, I had taken several Spring lectures before this lecture, Even though it was a basic course, it was not easy for a non-major + Java student who only saw it once..? I followed the hand-coding and listened to the explanation, but I was confused by the confusion of not knowing. Even after receiving the certificate after completing the course, I was in a state of chaos of 'Do I really know this?..?', so I actually put aside my high expectations for online lectures. However, after going through the entire process from development to deployment through this lecture, I now understand a little bit! There were only a few fragments floating in the air, but these guys finally started to organize it inside me as they got a feel for the structure. If I go back and listen to this lecture again and listen to other lectures, I think it will sound different now. The best part was that after implementing the code, he explained step by step why this work was needed and what it was for. In particular, whenever I asked questions like "Why? Why this?" while following the code, he kindly explained it to me right away after a minute, so I didn't have any special questions to ask^^ When I asked questions, he answered quickly and provided detailed explanations that weren't in the lecture, which were really great! In particular, since I had memorized annotations mechanically until now, I didn't know why they were needed or what the logic was, but I was able to understand them a little and look them up on my own. The most impressive part was the part where he separated the Controller into Service - Repository in three stages! I applied it to my work the next day after listening to the lecture. I succeeded in separating the code I was working on, which was a mess and focused on implementing functions, into three stages, and I even remember it more because it was so neatly organized! In particular, when I found myself calmly identifying the cause and solving it without panicking when an error occurred, I was really proud of myself. And instead of just saying I don't know... I was able to calmly practice reading other people's code! I've improved so much in such a short period of time, right? Haha At first, I thought, "Is this how fast the instructor speaks?" But instead, since he shares his knowledge step by step, I can understand it and the speed of his speech gradually gets better. I'm just a newbie, so yes, I still have a long way to go, but I'm deeply grateful to the instructor who has lit a light on this uncertain path. I'm already looking forward to the next lecture...... When will it come out??^^ I'm always paying attention to the instructor's steps (It's scary, right?? Haha) I'm rooting for you!! I will continue to improve in my own way, Thank you!
