I'm a 3-year university student and a graduating senior, but I don't have any basic knowledge of Java, so I listened to it from the beginner level, and it was good to be able to go through it again because I remembered what I learned before. But I always feel this way when coding, but I can make up for iterations and arrays with effort, right? When I have to use arrays and iterations, I feel scared and wonder if I can do it. I wonder if it's okay for me to not be able to code like this even though I'm a graduating senior. I wonder if it doesn't suit my aptitude, and my goals are high, but my will and brain don't seem to be keeping up... . Still, I'll try hard to study from the beginner level to the basic, intermediate, and advanced levels. Thank you for making such a great lecture. I'll study hard and get a job at a good place.
