As a job seeker who couldn't go to Seoul due to poor financial circumstances, you gave me the opportunity to learn a new technology called JPA, and the practical direction you gave me while teaching was like a ray of light to me. You also recommended a book about objects, which gave me the experience of thinking about objects from a new perspective. I haven't finished the lecture yet, but after completing it, I feel excited and energized about what kind of project I will create using JPA. Thank you so much for the great lecture.
