I think I was able to finish it without difficulty because you explained it in the simplest and most understandable way. I am currently a third-year university student, and as someone who has taken a Java programming class before, this lecture was a time for me to review and organize the key contents. Now that I have finished the introductory course, I think it is also the beginning of the future. Java is a difficult language for me, but it is the most interesting language, and it was a really fun time. I will not lose this mindset and will continue to listen to Professor Kim Young-han's stories and lectures to grow further so that Java can become a powerful weapon for me! Thank you for providing such a valuable lecture for free! It was a meaningful time!! I ask for your continued support!
