After listening to the lecture, I was able to create a mini bulletin board with CRUD functions in Java format among Java format and XML format. This time, I'm going to create it in XML format. So I'm going to go through the lecture again! I'm in a hurry to create it, so I feel like I'm gradually losing the concepts I learned, so I'm going to watch it again step by step and follow along to practice and study the concepts again. Thank you for the great lecture. :)
