I'm a total beginner who started learning Java about 2 months ago. I'm studying by reviewing every chapter of the lecture, applying it to my own code, and then looking at the book again, so I'm progressing slowly, but I'm progressing through the curriculum without difficulty because you teach me the basic principles one by one. I want to quickly run Spring and JPA twice each and mix all the lecture content to make a small toy project. Thank you so much for the great lecture!
