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

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.

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

Nice explanation sir..

Thanks Sir

Thank you.

Great explanation. Thank you!

What is created first a class or a stack

My first nice video on Memory Management 👌👌

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

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

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 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?

great explanation 👏

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

Great explanation

Best content on memory management..Thanks for sharing!

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

Nice Explanation

Hello Sir, I have some questions:
So where exactly are new Strings stored (in heap or in stringpool directly)? And where is the stringpool located then (method area of permgen or heap)? There has been some changes in Java 7 and 8 to the permgen section. When does a string automatically move to striingpool provided intern methos is not called.
Thanks in advance :)

This was really helpful. Thanks a lot.

awesome man

Is this java 7 model or java 8?

Hi Naveen, How to perform GC for a particular object

This is for Java 7 and lower. Please modify the video title to mention it is for lower version than Java 8

Best illustrated concept of memory management in java

Can you please explain the difference between java 7 and java 8 memory management .

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

very very nice explain

I become subscriber because this video

Thankyou for this video Naveen!

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?

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

nr.1

Very informative. I have one doubt why the survivor memory classified as two, both have same usage and purpose?

hello thanks for the videos i have a question:

public c l a s s B e e rA p pli c a ti o n { // Main Cl a s s f o r t e s t s

public s t a t i c void main ( S t ri n g [ ] a r g s ) {
B o t tl e b1 ;
B e e r B o t tl e [ ] pack = new B e e r B o t tl e [ 3 ] ;
b1 = new B o t tl e ( 5 0 0 , 4 . 5 ) ;
B e e r B o t tl e b2 = new B e e r B o t tl e ( 3 3 3 , 4 . 0 , ”Corona ”)


for ( int k=0; k<pack . l e n g t h ; k++) {
pack [ k ] = new B e e r B o t tl e ( 3 3 3 , 4 . 8 , ”Bi t ”) ;
}
where does the int k go on the stack or heap? thank you

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.

Thanks for sharing this knowledge!

we call a method , a method block is created what if we call another method from within a method
a new method block will be created?? if yes, then where inside the same method block or outside that method block?

Very nice👍👍👍 it's really helpful.

Such a quality content ❤️

This video deserves more likes and views 🙏

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 ?

great information, fine details. :)

Bow down to u ...TY so much

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

Thanku sir can u please share if u have any notes?

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

Thankyou sir for this 🔥🔥🔥 explanation

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

Hi Naveen, just want to know each application create own JRE on server memory? also what is difference between JVM and JMM?

Great explanation..
