Hello, Younghan! First of all, I would like to thank you for creating such great lectures. I am a job seeker who is taking Java Camp Backend Developer Training. I have taken all of Younghan's lectures, and now I am eagerly waiting for the next lecture. Haha I have taken many other lectures, but Younghan's lecture was really shocking when I first listened to it. The energy of enjoying programming itself was transmitted as it was. It was like watching a child playing with his favorite toy. Watching him enjoy his lectures while handling all those busy tasks, I thought, 'He really loves programming.' His teaching skills were also so excellent that I thought, 'How can he explain it in this way?' I feel so lucky to have taken Younghan's lecture. In the past, I only had a goal for getting a job. But when I saw Younghan, I thought, 'I should become a developer who enjoys developing like Younghan.' If I do that, won't the job come naturally? And I also thought, 'When I become a senior developer in the future, I should have a positive influence like Younghan.' My dream is to collaborate with Younghan. I will enjoy it and work hard to make it happen!! As for feedback... There really isn't any, but if I had to say something, the log output to the console was covered by the cam screen so I couldn't see it well. The log output through the logger was slightly to the right, so it was covered by the cam screen so I couldn't see it!! I think it would be better if you scrolled once. Hehe Once again, I sincerely thank you for the great lectures. Then I'm going to go review the JPA roadmap again...ㅎㅎ ps. Your throat looks really soreㅠ The lecture is important, but take care of your health!!
