I finally completed the Java roadmap.. I was struggling to study on my own, but thanks to Young-han's lectures, I learned what and how to study, and by grasping the big picture, I feel like my study direction and efficiency have been corrected. I'll be starting a backend bootcamp next month, so until then, I'll study Spring hard as much as possible! Thank you always for the great lectures~ I won't forget to review Java from time to time!
