I went straight from the basics to the basics, and it was a really good lecture. It felt like I was opening my eyes to a new world called Java, and as I progressed through the lecture, I could feel the process of simple but long codes becoming simpler and more advanced, and I could feel for myself that this is programming. If we go into detail, the lecture was organized so that many people could understand it step by step by spending a lot of time on the object-oriented part that many people find difficult, and in particular, the short but essential tip that he always emphasizes, "In Java, assignment always copies the value in the variable," was a great help in understanding the parts that I was stuck on. I highly recommend it to many people!
