I dreamed of being a developer, but I never knew Java in my life, and now I'm following Kim Young-han's lectures and doing web development with Spring. It's not just a simple listing of Spring's functions, but I was able to build a solid understanding of Spring by following Spring MVC with low-level libraries. As a side note, I think I have a scholarly learning style, but this time, I'm going to try something new with the help of Kim Young-han's advice. I hope it works out well.
