Among developers, Got Young-han's lecture was highly recommended, so I happened to listen to it while I was looking for a Java lecture. I'm so glad and grateful that I got to start Java with Got Young-han. I listened with interest because he gave clear explanations and even told me what it's like in practice. Although it was my first time learning Java grammar, I think I was able to learn it quickly because the lecture was well-organized. While listening, I often thought it would be nice to hear CS knowledge such as data structures and algorithms from a developer! Thank you for giving me the introductory lecture for free. I'll see you in the basic lecture. Thank you!
