I learned Java through books or at the academic level. In the process of reflecting on myself, I only learned 'how to use Java', but I was using it without knowing how it works. When I listened to the lecture, there were things I already knew, but there were also things I vaguely knew, and various stories that I couldn't hear in lectures that simply teach how to use Java, so it was very good. The stories Hoon tells and the content that he gives in a detailed way are secretly fun, so I listen carefully. There are lecture materials, but it's better to understand it because he explains it in real time with a pen! You said during yesterday's live broadcast that part 3 might come out at the end of December, so I'll wait! Thank you for the great lecture.
