Thank you for the great lecture :) I'm a non-major who just started studying development, but you explain it really easily, and the lecture content is neatly organized in PDF files, so I think it will be very convenient when reviewing.. I was lucky to be able to learn Java through your lecture! I haven't mastered it 100% yet, but I think development is somewhat suitable for me, so I plan to listen to the roadmap in the future! Please take care of me in the future. ㅎㅎㅎ
