I am leaving a review after completing the course. I enjoyed the lecture that combined object-oriented, Java, Spring, and design patterns. It was a lecture that allowed me to understand Spring more deeply. The pronunciation and speed were appropriate, and Tobi explained the Spring principles to beginners in his own way, so it felt a bit easier than the previous lecture. However, if there is anything to improve, 1. It would be good if you provided a document that summarizes the important content in each lecture with images and sentences and explained it while looking at it. If you just look at the presentation slides and listen to the long explanation, you may lose focus and not be able to hear it. In such cases, you may turn on the subtitles, but even that passes quickly, making it difficult to understand the overall context. 2. I wish there were more practical content or advice. I hope there will be more content that will be helpful to ordinary students like me who are still developing in a rule-based manner. I enjoyed the lecture. In fact, I am happy just to have Tobi's lecture. Wow, I am taking this class with the expectation that my skills will improve rapidly if I listen to this lecture. So I will wait for Toby's very simple lecture. Thank you.
