Amazing explanation sir. I haven't watched such detailed and knowledgeable video about JVM yet. Humble request to create more videos regarding Java. It will be very helpful. Thanks.
This is a really well-researched & well-written, informative video. The only thing that bugged me a little was the voiceover. Why is it mono? I could only hear it on the left channel and that makes it hard to concentrate. Thanks though.
Great explanation. One of the questions I had was regarding the Execution Engine. Since it supports both the interpreter and JIT compiler, you have mentioned that the interpreter executes the bytecode and the JIT compiler compiles the entire bytecode into machine native code. Does that mean that ,in case of JIT compiler, the OS would be responsible for executing the native code, whereas interpreter works independently of the OS and executes the code directly?
@@imranwahid9871 This works as I have mentioned. The JIT compiler looks for the frequently executed code and converts that code into machine native code and then that code is executed by OS. In case of interpreter, it works independently of the OS, that is why Java follows "write once, run anywhere" philosophy as the bytecode is independent of the underlying OS.

Siben bhai..Today i just saw your video in E-Learning Bridge RUclips channel ...there u say u passed out ur B-Tech from BBSR, and u r from Cuttack..and in Amazon you create the Bill payment section...i am very excited and so happy .. I am from Odisha, Nayagarh...now I am a continuing my B-Tech in GIFT, BBSR..in the branch of Computer Science . I am a 3rd year student . I want to know more about what is actually a Software Engineer work, and I am very poor in coding, i understand easily the process of coding but i am unable to think and what to write the next step in coding .Please gave me some suggestions to how i am improving my coding skills . I want to know briefly and concept of coding. I want ur guidelines please.
Hey Prayash, you should start practicing on Hackerrank. That is a easy and methodical place to learn and practice coding. For projects, there are so many resources on RUclips you can follow, depending on whether you're interested in frontend or backend.
You should have kept Dual Audio bro ... Why did u have to do to make it only left ? Or was that by a mistake ? Plug in headphones and listen you'll know
I am using Noise Cancel headphones. High base due to that. Content so much good. Same feeling. Please remove Background music and mono audio. Thanks for the content.
Hi, great video but I have a question. When you introduce method area, you say that the fields name and age are stored in method area and next you said that all instance fields are store in the heap area. I'm confuse.
Hi. The variables name and age are stored in the method area. However, when you create an employee object, that object instance is stored in heap area.
I was taken aback by the loud and that fast pace intro music bruh.... I was at the maximum volume of the headphones and my ears took some recoverable damage but bruh I request you to tone it down and keep it mellow.
Hii , Currently i'm working on TCS Pune , they forcefully allot me on support project. I joined TCS april 2021 nd am 2020 batch passout from IT stream. really I'm not intrested in support ....I have good command in java then what should i do. plz plz plz reply. Thanks
Java is Slower, BECAUSE, More Code is Running. That Code is Checking Security (Array out of Bounds, buffer Overflow etc). That Checking, Is ALSO Happening in the HARDWARE DEBUGGER. THE CPU is SLOWER.
This is one of best explanations of the JVM I have watched. The slides are really clear and well thought-out as well.
Thanks Quincy 🙂

what an explanation from 10 year experience person. Cant believe you have only 10 experience. Fantastic effort.
Thank you for a good and informative video. Currently working on an assignment about the JVM.
I'm glad I found this video before wasting time on other superficial explanations. Thank you Siben.
one of the most concise explanations of the JVM available. very nicely articulated !!
the voice audio comes from only on the left side , while on the other side there is music. It makes it very in-convenient to watch the video
It's kinda sad that you have only 3 videos. Thank you for your clear explanation!
I read the article. It was super awesome and easy to understand.
Thank you 🙂
Great tutorial. Clearly explains how the JVM works. Thank you for sharing.
Just what I was looking for man. Brilliantly put together. Thank you.
Glad it helped!
very nice exaplanation of JVM architecture with its working
Thank you sir very nice gide & very nice best information jvm architecture teaching video.👍
Amazing explanation sir. I haven't watched such detailed and knowledgeable video about JVM yet. Humble request to create more videos regarding Java. It will be very helpful. Thanks.
Great explanation, thank you. Keep up the good work.
brilliant!!!
pls come up with more topics in Java. Thanks
Hi siben,
Great explanation. Please keep posting and sharing knowledge
Hi Sir. This is the best source to learn about JVM. Thanks for helping all of us. Please can you do the same for Tomcat as well.
Great content and very detailed.
great conceptual video.
I have subscribed and liked this video.😉
Nice video bro..Thanks for sharing your valuable knowledge 🙂
Thanks 🙂
Nice work. One thing , the voice only in left-channel before 19min, and that sounds a little imperfect with headset.
Yeah that was a technical glitch :(
You explain so easy to understand ..thank you 😊
Thank you for the sharing the awesome content...
Unfortunately only one side of my brain understood what teach🙂 ( audio issue :-) )
Thanks a lot for this explanation!
Nicely explained, Siben. Keep up the good work.
Thanks Ganesh 🙂
excellent video !
Glad you liked it!
You are my hero.
Excellent explanation sir👍👍
Please make more on java 🙏🙏
Like arrays, strings,oops,constructors,etc.
Thank you so much sir 🙏🙏
Thanks Aviral. I'll continue to create more such videos.

Very good explanantion. Just one suggestion - The background music is disturbing, Although your voice is loud but its still not working out.

I also have the same question. Please share the answer if anyone knows about it.

jit compiler has the following - 1 intermediate code generator
2. code optimizer
3. target code generator
4 . profiler
so the target code generator converts the bytecode to native code then what is 1. intermediate code generator does

Thank you for the video. Is that hard to write an example on JVM,? If not, It would be great to see and follow that video. Thanks again.

@@theawesomenayak Ok so the names of variables are stored in method area and the value in the heap. Thank you

I joined TCS april 2021 nd am 2020 batch passout from IT stream.
really I'm not intrested in support ....I have good command in java then what should i do.
plz plz plz reply.
Thanks
Prepare DSA and switch
@@theawesomenayak Thank you for reply
pleaes keep dual audio
Left side audio not working 😢
METHOD AREA = PERMGEN??
Voice is very low
Interpreted Languages - executed directly without having to compile them
Is part is totally wrong ...
