Hello, Younghan. I am watching the lecture well. The textbook PDF file is well-organized, so I am studying the textbook first and only watching the lecture for the parts I do not understand. I have just started working and am working on the job, so I often use the Java module system. However, I am worried because there is no content that organizes best practices or practical content related to the Java module system. Do you have any intention to cover this part as well? In addition, as I work on the job, I will use streams a lot, so do you have any plans for Java functional programming? I have become a question mark killer, but I am also curious if there will be additional updates regarding virtual threads that were recently introduced in Java 23. (In a format that can be used in the field!)
