There was some content that was a bit different from the book... but since it's a book that was published a long time ago, I was able to learn about the latest(?) techniques. Since I just skimmed through Java and went straight to the lecture... I didn't have knowledge about jsp or other things.. so it was quite difficult... I'll have to go through it again next time... It was a lecture that wasn't boring and contained a lot of content, so I discovered a "me" that thinks deeply. Thank you for the good lecture..!
