I learned Java superficially with government support, so when I was working on a web project, I didn't even know the basics and just copied and pasted, so I was really depressedㅜ There were many parts that I didn't understand why the code was written this way, but now I understand after listening to the instructor's explanationㅜㅜ Thank you!! If you want to build a solid foundation in programming, you should definitely listen~
