The best instructor and the best lecture. Thank you so much. I wanted to learn from the basics, but I was so worried. I was worried that I would be able to learn objects, even though they are basics. Thanks to the best lecture, I think I am getting used to it. I will review it a few more times. Even though it is an online lecture, it is like listening to it at an academy. I was able to concentrate very well and did not want to do anything else. I listened without realizing the time passing. Thanks to the lecture that was easy to understand and made me feel comfortable, I think I am not doing anything else. Thanks to you, I am challenging my childhood dream that I had given up on. I want to learn Spring quickly. Thank you.
