The best video on memory management that I have come across. It gives a clear insight on how to write memory efficient code in Java. Will appreciate if you can make a video on streaming and how it works internally. Thanks a ton.

This video deserves more likes and views 🙏

Best illustrated concept of memory management in java

Great explanation. I read that from Java 8 onwards the permgen has been removed. And instead of permgen we have a metaspace which is part of the native memory (which is not a heap memory) which is managed by the OS.

Great video. JVM understanding is important not only for interviews but far beyond interviews.

Thanks a lot Naveen. That was a Video which I was looking for it but never could find. Thanks for the excellent explanation.

Thank you provide valuable information about Java memory management 🙏🙏🙏

Best content on memory management..Thanks for sharing!

Very good video....!! Crisp and Clear...!!! Thank you...!!

Hi Naveen, as always this is nice explanation!! Can we say that :Java Stack memory=Class (method) area+Native Method Stack+Variables memory area

One of the best tutors you are Naveen.

I am always follow your channel for java related , you rocking pls keep doing the good work. great sir!❤

Sir you have clear all concepts regarding java memory management. Thanks for your such great efforts in making video.

Awesome explanation!!! Terrific!! Thanks a lot!!!

Great knowledge you having sir. Thanks for this .

really it is very nice video, after read this, I clear my concept on memory heap and stack. thank you navin.

Great Explanation , this is something that I found deepen understanding of memory management. Thanks Naveen

never found so detailed.... thanks a ton!

Very nice👍👍👍 it's really helpful.

I Like your efforts Naveen, Very very useful video for interview (I was asked these questions in mine!).

Kutha chimpi para dhengaw anna.... Mid nyt kuda chaala interesting ga chusaa

Great explanation. Thank you!

Thanks Naveen for this amazing video. It is full of information and explained very clearly.

My first nice video on Memory Management 👌👌

Just thank you.. i relieved finally.. i ve been seaching this for years !!!

Thankyou for this video Naveen!

I really appreciate your effort Naveen. Thanks for video :)

Thankyou Naveen. This was so informational

Thanks, very interesting video. I just wanted to see what is the diference between local and static variable storage but I've learned much more.

Hats off sir..very good explanation.. Pls continue this topic to cover garbage collection..

Great and deep explanation and information in detail . Better than all other videos from other youtube channels.. Just a small suggestion, if the diagram is ready then this video can be covered in bit less time.Awesome video. Thanks a ton

One of the survivor memories will always be free..

Nice explanation, thank you...As for the back ground noise, you could add a faint background music to cancel and soften the high pitch noise....

It was really a very explanatory session. Got all the concept by this vesio

Great explanation

Very good explanation for Memory management. Thanks Naveen

Nice explanation sir..

Nice Explanation

Thankyou sir for this 🔥🔥🔥 explanation

great explanation 👏

Naveen, i want to add one point, permanent Generation is part of heap memory not stack memory as you said in video(28:03)

Every Nice explanation sir, it's very clear to understand. Thank you sir.

Great explanation..

Bow down to u ...TY so much

This was really helpful. Thanks a lot.

Thanks for sharing this knowledge!

Thank you so much for creating such a helpful video

Great video. Just had a couple of query : 1. You said permgen is part of stack memory but you displayed them on separate boxes so that was confusing. 2. You said stack size is very less compared to heap memory. but than what about Permgen (or now Metaspace) . Is metaspace is less compared to heap? Thanks!

This is perfect! Great job man ! Thanks a lot!

u really make it simple naveen... 😊...i still like ur amazing diagrammatic representation of concepts which make things really easy to understand...kudos bro... keep going...👏🙂

Excellent sir, thanks for the video

Very good explanation. But this video is up to Java 7. Java 8 on wards, we dont have pergem concept at all. Its Metaspace now.

very very nice explain I become subscriber because this video

Good explanation

Thanks much for sharing the information.

Very well explained .. Concise and clear .. Pls keep uploading more videos on JAVA

Permanent Generation is also part of Heap memory.

Great Work, I searched so many videos but this is my final stop !! Appreciate the efforts you did to make this :) One doubt : Is permanent generation the part of Stack Memory ???

Naveen ji extraordinary teaching thanks a lot for sharing your great knowledge please help in sql concepts as well.

how you differing method block and method area of Permanent generation.

Very informative, but I was looking for information regarding MetaSpace.

sir , your explanation is very nice and make more videos thanking you very much sir

Small correction in your lesson When the survivor space S0 is filled, it automatically goes to Old Generation after the minor GC. It will not go to S1.

Such a quality content ❤️

Thanks Naveen for such a informative video. I have a follow up question below:- If we create any Collection I.e Arraylist , Hashmap etc .. where is it created .. in Heap or Stack?Since collections stores the the object references rather than physical objects..How does it manage the whole process?

great information, fine details. :)

If Test t = new Test() is defined as instance variable rather then defined inside some method like m1 method. In that case I understood that new test() will be creating one object inside the heap. But where the reference will be stored as it is not local variable it is instance variable ? And stack will store local variable and local references as much as i know?

Very Good One:) got some more Idea about JRE.

Excellent! Thank you so much.

one word....AWESOME

method area is inside the permanent generation, so can we say that now method area is inside the metaspace

Permanent Generation is replaced by Metaspace in jdk8. What's the difference

Thank you so much Naveen but one Question, Cam you tell from which book you took reference ?

Thanks for such nice videos....can you please tell me after execution of a method... where the result is stored.???

Question 1: At the time of Major GC, will the JRE do only Major GC ? or JRE will perform its normal tasks and in parallel Major GC will perform Question 2: When you said we don't have to do the Major GC frequently, is there any code we write explicitly for GC? I think JRE itself take care of the Garbage collection.

Thank you.

What are JRE classes? The predefined classes or the ones which I have made ?? Someone help me understand please.

Very informative and nicely presented. Just the keyboard noise is lill irretating. Please upload any video on Class loading with context of JRE.

Clearly explained ....

Memory leak will come on only in heap area right? If yes then in that case what we need to do in that case?

Hi Naveen, How to perform GC for a particular object

PermGen was part of Heap upto java 8. From java 8, it had been removed.

awesome man

Nice Naveen, very informative. :) by any chance any plans for a video explaining the metaspace concept also?

Hi Naveen, Thanks for the explanatory video. It's really helpful. Just a small doubt, somewhere I read that SCP will get memory inside method area, you told it would get memory inside Heap... If you can explain more about SCP it would be helpful. Thanks again ☺️🙏

As much as i have a knowledge till now permanent generation is separate memory are and stack is separate memory area . But in this video somewhere at the end you are saying parmanent memory is part of stack memory which is making me confused can you please explain on that ? Is both separate memory area or parmanent is part of stack. ?

If m1 calls m2, method block will be available to which method?

sir can we say that each class have only one object and rest are created by referenced to that object.

Hi sir I have one doubt,let say if older generations is also filled with objects and there is not enough space then if GC destroy that object wouldn't it impcact the application as the object is no longer available...sir I am starter guy pardon me if I sound stupid..

As per my understanding, 1. So at a time, one of the survivor space is always empty ? this correct ? 2. Objects that are survived after many cycles of GC, are moved to the Old generation memory space ?

PermGen is replaced with metaspace after java 8 with better memory management and growable feature.

Thanks Sir

Custom immutable store into which part of memory?

Ty. Good explanation

Very good

hi naveen nice video...its very help full to understand the memory concept....... is there any hidden memory concept in java

What is created first a class or a stack

Its really helpfull..thank you

Great one!! One question to you Naveen. Do you know how to perform test for the product (Web based Game) where DOM element is hidden. I think all the DOM element is under the CANVAS?

Thanks boss
