I really appreciate you for working on the lectures with so many pictures, from CS basics to practical application techniques for multithreading and concurrency. Thanks to you, I was able to learn Java multithreading techniques and concurrency issues, and I think I can appropriately utilize the content you taught me no matter what language I use.ㅎㅎ I enjoyed the lecture more than Kim Young-han's Practical Java - Intermediate Part 1! I think it's really meaningful in life when I can help others, and I think Young-han is really helping so many people. You may be tired and exhausted when you create lectures in the future, but I'm sure that many people will benefit from Young-han's lectures and that those benefits will spread to more people. You've really worked hard. I'll see you in the next lecture!
