Hello. Professor Kim Young-han! After leaving a review for the Java introductory course, I promised myself to leave another review soon, and I did it...! Just like I felt during the introductory course, this course made me realize how messed up my concepts were before I took the course. Of course, I couldn't solve the last example on my own, so I had time to follow along and understand it while watching the teacher implement it. I think I need to review it again and make it mine before moving on! Thank you for making such a great course. I want to listen to the intermediate and advanced courses soon, so I shamelessly ask you to do it a second time...! Please play a little game ㅜㅜ
