Stack and Heap: Memory Management In Java (The most important Concept in Java)

From Java Code to Java Heap: Understanding the Memory Usage of Your Application:

Understanding JVM Memory Model, Java Memory Management are very important if you want to understand the working of Java Garbage Collection.

You might think that if you are programming in Java, what do you need to know about how memory works? Java has automatic memory management, a nice and quiet garbage collector that quietly works in the background to clean up the unused objects and free up some memory.

Therefore, you as a Java programmer do not need to bother yourself with problems like destroying objects, as they are not used anymore. However, even if this process is automatic in Java, it does not guarantee anything. By not knowing how the garbage collector and
Java memory is designed, you could have objects that are not eligible for garbage collecting, even if you are no longer using them.

So knowing how memory actually works in Java is important, as it gives you the advantage of writing high-performance and optimized applications that will never ever crash with an OutOfMemoryError.

On the other hand, when you find yourself in a bad situation, you will be able to quickly find the memory leak.

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.

Best illustrated concept of memory management in java

[ABAutomationHub]

Best content on memory management..Thanks for sharing!

[ananthasubramanian]

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

[WeWalkAI]

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

[TechWithChetann]

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.

[niloybasu]

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

[nandagopal]

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

[akado]

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

[rachanabanerjee]

One of the best tutors you are Naveen.

[avishsharma]

[jaserq]

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

[prabhatpatnaik]

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

[jalalzoon]

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

[Saravanans-qe]

Great knowledge you having sir. Thanks for this .

[meditationandrelaxationmus]

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

[praveenautomationinterview]

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

[saranthoughts]

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

[SeadoooRider]

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