I completed the Java Basics course after the Java Introductory Course. I had already learned Java on my own, but I took the course as a review. The lecture content was really good. It was easy to understand with easy-to-understand pictures and the explanation was good from a beginner's perspective, so I understood it really well and it felt like it was imprinted in my head. Thank you for making such a great course. + Please hurry up and give me the intermediate course after playing the game ㅠㅠ.
