If there anyone dicided to complete the video Just liked the comment. Your like remembers me to completed it.

I want to share something. I am a Sri Lankan. After getting selected for university, I had no idea what I should learn or where to start. I didn't even know what a framework was! ​By chance, I came across your video about Java, and I started learning it through your video series. I also shared it with my friends and told them to watch it because it was so good. After that, I watched your Spring Boot video series, and I even did my final university project using Spring Boot. ​Honestly, I didn't have the money to buy separate courses to learn these things. Today, I have a job working with Spring Boot, and it is all because of your videos. Thank you very much.

Java course ❌ Java degree ✅

Agentic AI with Java live course : https://go.telusko.com/agentic-ai

It took me almost one month to complete the course, and I learned a lot from it. The course was very good, and all the fundamentals were clearly explained. However, it does not explain topics like AOP, proxies, Reflection API, and also lacks depth in JWT/Spring Security authentication. There was no explanation of refresh tokens vs access tokens, which is an important concept. Apart from that, the rest of the course was really great. If, in the end, there were a full-fledged project using microservices and other advanced concepts, this could easily become one of the best courses on YouTube. Still, getting all this content for free is amazing. Really grateful — thank you, Telsuko team! And sorry if this review sounds demanding. Humans never stop demanding when they get something valuable for free 😄
