[cplearners]

The moment whenever he says "respond man", I feel like he was in front of me and starts answering. Best teacher ever

[devang.jayswal]

A BOY starts LOVE with the word FRIENDSHIP, but GIRL ends LOVE with the same word with FRIENDSHIP. Word is the same but attitude is different. This beautiful concept of OOPs is nothing but Polymorphism. 😂😂😂

[prabhanjanborkar]

"Compiler will give left-and-right" 😂👀😂 echoes in my ears everytime I code.

Even if I'm well-versed with the Java course, I'm still fond of Durga Sir's teaching and in-depth explanation; I'm still rewatching the entire course video to brush up my concepts.

[mdsaddamkhan]

2:30 hours have been passed but I am still willing to go further.... I have 6k paid course from udemy I didn't get that much of clarity that Durga sir provided .. thanks a million sir... Love from West Bengal

[damodaranm]

Legendary . trainer i have nerver ever saw any such savage guy who teach java in tthis waay . even a 10 times attempt 10th std student can able to understand java if this legend trains him

[eyerahulk]

I learned python from durga sir, got offers from tcs, infosys and accenture. Joined TCS last month, they assigned me java course on their internal platform to learn, leaving that I am learning from Durga sir here on youtube just because I am addicted to the way Durga sir teaches....Much love for you sir. You are a True LEGEND.

[ayushshrivastav]

Sir is teaching like our childhood teacher teaches us ABCD
We will never forgot ABCD, same way we will never forgot java... The way he teaches us everything gonna fixed in mind....🔥🔥✔️✔️

[devang.jayswal]

I haven't found teacher like him ever before in my life. Durga Soft rocks 🔥

[ashishpanchal]

happy teachers Day... with the help of your videos i got placed in MNC...THNK UH SO MUCH SIR

[letsfightagainst]

The best ever teaching vedio of Java in YouTube..even non computer science people can become softwares by his teaching

[adityashrivastava]

Your way of teaching is Outstanding sir, I watched 3 hrs of video without being bored for a second...."Compiler will give left and right " is hilarious🤣🤣🤣

[Itz_Anim_Hub]

I had my viva today and they asked me 5 questions. Among 5 questions 4 questions came from this video thank god I watched this before
I understand every concept in this video and you are the best 👍💯 teacher

[aryanaboyaryayeenezhad]

His absolute hardworking and outstanding job is highly appreciated. I wished we had many of these kind of great and dedicated teachers.
Thank you Mr. Durga!

[undencem]

Best series of OOP tutorials . I have already finished them and I really improved my OOP knowledge . Thanks to Durga . Greetings from Turkey

[ShailPanchal]

Respond
The compiler will give left and right.

Great lecture...very thorough

[santhoshrajvysyaraju]

I completed total lecture in a day with full of joy... #Lockdown... Awesome lecture..funny... interesting... brainstorming... knowledge sharing...👏👏👌👌

[ssharma]

I normally don't write comments, but writing this to appreciate Durga Sir's teaching style. A well explained, detail oriented course on OOP!
I completed only two and a half hours and still needs to go up to 10:33:30, but I have a feeling that I will gain a very solid knowledge on OOP concept from this video.
After completing this video, hopefully my compiler won't give me a lot of "Left and Right" :)

[gauravgupta]

Whenever i hear word java....Durga sir is the first thing comes in my mind 😁😁. You are a legend sir.

[CoffeeMViralVs]

you got the best camera man. You Durga created your own CLASS Level . Good job indeed sharing with world.
