Love how you don't say any unnecessary things and get straight to the point without wasting time

[v.karikaran]

I am impressed by your dedication and hard work in watching a 12 hour long video on Java. Your effort has paid off and i have gained a deeper understanding of the language. Thank you to the instructor for providing such comprehensive and informative content. Your video has truly been a valuable resource in my learning journey. Keep up the great work!
Thank you sir !!

[AboinTech]

This guy is a legend, I have learned everything I needed about JAVA just by watching once even in 2x. Amazing work, and thank you very much.

[akhileshsohotoo]

Teachers like him are changing the world by providing such informative contents for free ❤. Not only his teachings are deep and simple to understand, he teaches with passion and dedication as well.

[GeekyGagan]

Hi sir, I am your big fan and I used to learn a lot from your channel in my college days 5 Years ago now I am working as a software developer in a good company but not on Java technology but I am always In love with java the moment I saw this video it feels like let's refresh the java knowledge again because no language can beat JAVA. Thanks again for the great content.

[gamerauto]

This is the best tutorial for beginners, although I'm not one, but I just love it. The only issue about this video is that it ends.
I want it to be of around 20 hours, you explained everything in a very straightforward and simple manner.
Hats of to you Alien. ❤👏

[nayanchafle]

East or west Navin sir is the best..!🤝 Loved this course..

[dzeblemartin]

Telusko i will keep on saying, you are invincible in your teaching. God bless you

[suhaillone]

One of the best teacher on YouTube.
I have learned java first time from you through your last playlist on java.
Whoever is new to java, this teacher is one of the best choice.

Starting this tutorial to prepare for my programming degree:

Day 1 -> 1:46:47
Day 2 -> 3:29:44
Day 3 -> 4:42:24
Day 4 -> 6:06:08
Day 5 -> 7:08:31
Day 6 -> 8:27:11

[dhivyaa]

I am preparing for a job after 3 year gap. Your video is very helpful to recall the topics. Thank u Navin

[varunmukherjee]

I am a software engineer so I kinda look for maturity in a course and most courses don't have that but this course really caught me off-guard. This course is by far the best course to learn core JAVA in entire youtube and is much much better than many paid courses as well.
Great work @Telusko 🙌🏻

[hemantraghav]

Greetings of the day Naveen sir, I know this going to be a great course on java. Please try to upload content like this on the Spring framework also.
