I have attended many other lectures, but I didn't organize them well, so I started listening after paying for the first time. The lectures are easy to listen to because the voice is nice and detailed, so it's easy to listen to. Haha, I don't regret paying the tuition at all.

Java basic concepts, learn them all at once in this lecture. Also, learn them through practical examples such as academic management program, daycare meal management, etc.😀
