I learned the basic grammar of Java at school and in other online lectures. I also read books. But I kept wondering what the word object meant. When I asked my seniors, they only gave me strange answers. I was really curious as to why people had to use Java for web development. So I started studying Spring right away even though I didn't know anything about it, but I felt stuck because I didn't have the basics. That's why I came to watch this lecture. Thanks to this lecture, I feel like I'm starting to solve the puzzle little by little, so I really like it. I hope the database lecture comes up soon.^^
