I loved the way you have merged the whiteboard series with the previous core java series from the continuation basis, such a detailed amazing job!! On top of the video being amazing as ever even the organization of it adds more sense and logic to the video. Hats off Sir!

Thanks a lot, Naveen for your dedication and awesome job. You are amazing! The beauty of your lecture and speech is you are not talking in an academic and boring style but giving examples from the real work env. with attention-grabbing manners. Again, many and warm thanks for your precious efforts. Follow you with great pleasure!

I have seen many tutorials of Java but not completely satisfied. After watching this tutorial. I got so happy that I have subscribe it from all my emails. Actually I was stuck with memory allocation that how does. Heap area or stack area or method area really work?🤔🤔🤔 Finally I got it 😁🙂 thanks a lot sir 💗

Hi Sir, Just wanted to know the survivor 1,2 part is it required for the automation.
I got confused after a while. I know the memory concept should be clear. But is it mandatory to go that much deep?

Hi Naveen
I have started learning selenium to switch from manual to Automation and I want to switch ASAP.
I know some basic Java and covered Selenium basic concepts till now.
Do I need to go through all these topics mentioned in Java playlist?
Please let me know . @Naveen

[@KaisarAnvar]

First!!! ❤️ You're amazing sir, about to learn so much from you. Are there videos of you teaching about API + Postman + Framework? My weakness is that I try to understand the intet-connection between these (and perhaps more) but hard to digest. Thanks so much!!

[@KaisarAnvar]

inter*

[@tarunsoni6971]

A question in the first 5 mins itself, you said that stack memory is LIFO and the Stack space for M1 and its local variables is at the bottom then how the memory is deallocated from the bottom... I am already confused.

[@ayush_goel]

Thanks for the video Naveen. I would like to give this feedback that there is sometimes lot of repeated information within the video itself. For eg., in this video, you repeated metasoace functionality more than twice which, I think, was not required. Other than that, great content

[@pradiptojha3611]

That t-shirt is epic..

[@ganapathyg981]

[@amolnawale2177]

Thanks Naveen for this wonderful topic on Java memory management. Learned Lots of new things. Do we also have any session covering the String Constant Pool within the Heap memory?

[@saxena3718]

I think this should be sufficient for any interview questions on JVM

[@Ashokkumar-wj5mw]

Hi Naveen, Can you please make a video on Spring cloud contract testing

[@gauravsalagare8120]

Thanks Naveen,
One question,
Where the string pool is stored, in heap memory or metaspace?

[@ADIL7777777777777777]

In heap memory they have allocated a special space to store string which is metaspace .

[@SachinSharma-fr1vb]

string constant pool is part of heap area where string literals are stored. Metaspace is different n not part of heap. Static members like variable ,methods are store in metaspace which take memory from native OS.

[@mahalasakini5045]

Sir please make some videos on SOLID principles

[@muthukumara8792]

Sir could you please make video on jre,jdk and JVM difference?

[@Ashlin63]

Hi Naveen,
Your video is very informative.
Can you please tell me what happens in below case?
public static void main(String[] args){
Custom[] getArr=getCustomArray();
}
public Custom[] getCustomArray(){
int a=10;
String b="Ashlin";
Custom[] customArray=new Custom[100];
custom[0]=new Custom();
custom[1]=new Custom();
custom[2]=new Custom();
.
.
custom[99]=new Custom();
return customArray;
}
As you mentioned that the stack frame for this method will be destroyed once the function exits.
But how does it work in the case of returning the value from a function? Once the reference variable is destroyed from the stack frame does the new reference variable in the calling function point to the Custom object in heap?

[@hritikmandal1491]

Sir in the 1st lifo concept. Those 3 methods will stored in stack sequentially when one method will call another method sequentially but here no call of methods or any kind of dependency from one method to another method so sir lifo or filo concept is going to work when one method will call another so the called method will be executed 1st and then the caller method will be executed or we can say released the memory. Sir if I am wrong then please let me know.
