I saw your OOP videos first and I prayed God that I find some videos for the heap and stack that you explain. I can't tell you how happy I was when I found this video. THANKS A TON :")
I went through multiple videos to understand stack and heap where there was some lagging but after seeing this video, it makes me clear. Thank you so much for explaining in detail
Thanks much Imtiaz, this video will be like a dictionary for me , you clarified lots of doubts which persists in my mind since long time Its a appreciable attempt to put this huge insight in such a short vid
Pretty good video. Thanks! But there are two important points you should've covered here: 1. Why does Java do this? I think the first question which comes to my mind is: why not store the objects on the stack too? 2. What happens when we call a method with arguments? For example, what happens when you call the method 'doWork' using that 'age' variable: doWork(age)? How do variables work then. Or if you call doWork with a reference variable, like myCar. Things get really interesting then :p Other things you could've mentioned, not necessarily though: 1. This is the right place for you to just give a quick mention of what a stacktrace is. That stack diagram with method frames is just begging for you to mention stacktraes in passing. :-) 2. For people who might have studied DSA, might be wondering: yes, that looks like a stack but why it that called a heap?
A ref variable can nvr call a method u fool. It is called by an object to which the ref var could ref to.it is done by instantiation.and then call the method by using dot operator.
Glad that I found this video. I have seen videos on LinkedLearning(Linda.com) Udemy, college classes no one explains this properly it's been 2 + years and now for the first time it makes sense to me that what this heap and stack are all about.
Imtiaz, I feel like sometimes I can hear your accent slip juuust a little. I can only imagine how hard it would was for to learn a language and really nail the accent in a clear, precise way for the native speakers you are teaching. Immense respect! Something I'm not sure I'd be capable of.
And that was all what you got out of this video, right? his accent and when/how he slipped out. I hope that you paid attention and actually learned something from what he was actually explaining.
@@MJ-cf9nl Can you chill maybe he's just a random stranger passing by and he's not even looking for learning stack and heap? You don't know for sure. Plus he's complementing Imtiaz anyway.
damn man you are so cool your English is fantastic even for those native English speakers continue your great job and please make new playlist tutorial
Sir The explanation is superb and clear. I haven't seen this much clear explanation on Garbage Collection and Stack Vs Heap. Thank You so much. Please put Videos on REST API as well.
Imtiaz: * Shows how primitive type save in the heap * Me: "Cool, but what about class objec..." Imtiaz: * Explains about class object * Oh man, thanks you :)
Very clear explanation. However you didn't mention in your first example (08:30) that String is a referenced Type. This could cause some confusion for viewers who could get the idea that the values of the String are stored on the Stack.
Great video! Just a little point missing: Once bigEngine is defined in main() in the stack, it has to refer to an Engine () in the heap (that line is missing) Then my3Car.myEngine is set to bigEngine in the stack which is already referring to Engine in the heap.
My question is this: in order to create instances of a Car, there needs to be a class named Car.java. so, in order to create Engines, there needs to be a class named Enigne.java?
Great job Imtiaz, Your explanation makes sense. But when I found your channel, I was looking for how to treat the static methods and polymorphim in memory, hope you can extend your explanation to accommodate these terminologies... Best Regards. Feras
Thank you for the video. I have a question that applies around 13:45. Let's say you define Car yourCar = myCar; (can you do this...I think so) This means myCar and yourCar point to the same memory location in the heap, as in your diagram. If you now define myCar to be a new Car(), am I correct this moves the pointer of myCar to a new slot...again as done in your video, but leaves yourCar to be pointing at your old car? Now myCar and yourCar are different cars....I am sure hope I got this.
Sir thank you i finally understand what i am confused about, other explanation confused me a lot rathan than understand it but you sir i finally understand.. i subscribed immediately😁😁😁
In my 15 years of professional Java experience I must say that this is the best explanation I have ever seen of stack and heap memory. Great job!
Is java is good to learn in 2021
@@Samad_27 Yes. Yes it is.
@NOCDIB thanks but one more question how to improve programming skills
Brilliant video, couldn't have explained it any better!

Not everyone learns in the same way. But, your way of explaining this makes a lot of sense to me, thank you for sharing such valuable info here!!
You have done a good job on demystifying the whole terminology things! You should be a teacher! Thanks for the subtitles too. Very helpful!
He is a teacher. He has a course on udemy. Check the descriptions guys..
The greatest explanation I've ever seen. Thank you, Imtiaz!
the way you explain stuff is just amazing . Your udemy video on class design got me a job in a product company . thanks a ton
This guy is really good at explaining, this is the best explanation I've ever seen of stack and heap memory.
well done !
WTF! This is the best video I have ever, EVER, watched! Who is this genius?! I am subscribing right now! Thank you, Imtiaz!
I went through multiple videos to understand stack and heap where there was some lagging but after seeing this video, it makes me clear. Thank you so much for explaining in detail
man, it was an incredible explanation with just a pen and whiteboard. Thank you
I'm going to repeat it step-by-step with my students.. Cool!
Explained Concisely. BRAVO!!
This is the best explanation I've ever seen about the stack and heap. Thank you so much!
You are a God's gifted teacher to all students n professionals. Hats off! Imtiaz.
With due respect, you deserve my like, comment and obviously subscribe. Thank you so much, sir.
I watch this every time, before I starting any new project.
One of the Super Best explanations I have ever seen.
That guy born with a gift of knowledge transfer, man!
I REALLY need this video at this time!That is what I have been looking for !Thank you so much. it has been super helpful!I appreciate it
Sir, I am completely shocked ! you are AMAZING ! thank you so much
Not all heroes wear capes!
I do!
Why this message here? Cant get it
Not all heroes spell 'caps' correctly
What can I say. You are very good at teaching! Thank you! I will definitely use your link to study more.
Great explaination......thanx ...now m able to figure out what actually goes inside jre
Awesome explanation bro, your hand writing is not a problem at all.
Great explanation!
BTW, String is also a class, so 'name' variable's data will also be stored on heap. (Like explained for Car)
The best explanation I got for stack and heap memory.
Thanks a lot sir.
Thanks much Imtiaz, this video will be like a dictionary for me , you clarified lots of doubts which persists in my mind since long time
Its a appreciable attempt to put this huge insight in such a short vid
clear explanation Finally found something explain the Java concept with pleasant to listen English :)
.
Hats off!! Brilliantly explained!!
You should be teaching in schools, wonderful explanation

You have a weak mind. All the primitive variables and references put inside method including parametrs reserve place in stack inside method block
A ref variable can nvr call a method u fool. It is called by an object to which the ref var could ref to.it is done by instantiation.and then call the method by using dot operator.
@@PandeyJii9632 Him asking a question and giving possible feedback doesn't make him a fool or a weak mind. Get over yourself mate
@@PandeyJii9632thinking curiosity is for people with weak minds is itself weak minded. Asking questions is one of the most important parts of learning
Great video! Best explaination I have found, thank you!
Excellent explanation, i loved it, thanks Imtiaz
WOW Thank you so much - I'm brushing up on my explanations of Java for an interview next week and this was incredible!
Glad that I found this video. I have seen videos on LinkedLearning(Linda.com) Udemy, college classes no one explains this properly it's been 2 + years and now for the first time it makes sense to me that what this heap and stack are all about.
Hey Thanks a lot, I am searching a lot to find what happens when we create a variable , The best explanation which I found...
Clear and concise explanation. Very enjoyable!

Oh man, thanks you :)
Great video! been looking for a good explanation for a while and finally found it.
wow this made a lot of sense, very great explanation
Very very well explained, Good job and please keep it up.
Very clear explanation. However you didn't mention in your first example (08:30) that String is a referenced Type. This could cause some confusion for viewers who could get the idea that the values of the String are stored on the Stack.
Very nice explanation! Understood all! Thank you!
It's the best video about stack and heap. Thnak you!

Once bigEngine is defined in main() in the stack, it has to refer to an Engine () in the heap (that line is missing)
Then my3Car.myEngine is set to bigEngine in the stack which is already referring to Engine in the heap.
My question is this:
in order to create instances of a Car, there needs to be a class named Car.java.
so, in order to create Engines, there needs to be a class named Enigne.java?
Håkan Ahlström yes of course. Since it's not a built-in class, it's our custom class.
Simple and superb, Nice explanation. Keep it up Man!

This was amazing. Thank you.
The best Explanation..
It's like listing to music not java😂😜
Ur explanation is far excellent 👌
Thank you
amazing mentor !!
good job explaining brother. Nice and clear
Hi Imtiaz, @13:59 you said myCar will contain the address of new object in heap. Wouldn't that cause error duplicate variable?
Great explanation, Thank you.
Sir thank you i finally understand what i am confused about, other explanation confused me a lot rathan than understand it but you sir i finally understand.. i subscribed immediately😁😁😁
