I think this is the first time in my life that I have studied to my satisfaction. I was so happy to be able to learn the in-depth knowledge that I have always wanted, and I think I learned not only Java knowledge through Mr. Kiseon's lecture, but also how to find official documents and reliable sources, study from them, and dig deep. Although it was a short period of time, I felt like I was training with a master in the field remotely! Thanks to you, I want to do better and grow more as a developer in the future. Thank you very much. (I hope I can contact you again when I am successful. Hehe)
