I am so glad and thankful for god, that kunal taught me Java!. Now i Love Java more than any other programming languages.. `ThankYou, So much Kunal`.. Keep going..🤠❤
At 33:51, I had this exact same doubt in the previous video and commented on it there, and now you've answered it here. You know all the doubts one can have. Amazing series so far!
I saw many java tutorials of other UA-camrs but the my mind is not clear at so many point. Now i'm relaxed . Lot of concepts are cleared thanks men! You are the real jem.
Great video!!❤️ Just one thing i want to mention is that at 33:43 you said it is internally doing but how it is inheriting the object class is because as child class inherits the parent class hence it can't inherit any other class(no to multiple inheritance), but we can see that parent is is inheriting the Object class hence child class is indirectly inheriting the Object class via parent class. Object -----> Parent ------> Child ----| | | |____________________________|

At 33.51, a subclass inherits the properties of the Object class, not through internal multiple inheritance, but through multilevel inheritance. This means that first, class A inherits the properties of the Object class, and then the subclass inherits from class A. Therefore, all methods available in class A are also available in the subclass because of inheritance.
brother you are the best.... following all your videos nd all have quality👌..bole to ek number 😉...U r just out of the crowd....nd at last thank u so much brother..u r doing great 👍
are bro i know c++ not java but once you understand the flow how things work you can code in different language no problem main thing is to understand the concept which is very well explained by Kunal
Good Explanation, But just one small correction when you say it is a multiple inheritance when your extended class also extending Object class. Actually you base class extends Object class and your sub class extends base class which extended the Object class. This hierarchy is an example of multilevel inheritance, not multiple inheritance. Eg- BaseClass (extends Object) SubClass (extends BaseClass, which, in turn, extends Object)
At 45:17, you're downcasting an object which can produce run-time errors. A more safe way would be to check if the obj recieved is an instance of ObjectDemo and then downcast it call num on it. I know you might have done it just to make us understand. But am i right in my conclusion.
a sub class also extends the object class because----> the parent class it is inheriting extends the object class and hence the subclass indirectly inherits the object class
Great Job Kunal! I have been waiting for you to finish this course from almost 6 months. You must be very busy so can you at least recommend someone's channel so that we can move forward. Please do reply to this.
Box box5 = new Boxweight(2,5,6,7); box5 is of type BOX, but it is referencing to an object containing the properties of boxweight. This is possible, even tho the constructor boxweight is present in the boxweight class we can access it using a reference but only those properties or instances which are common in both BOX & boxweight. It is the type of the reference variable and not the object that determines what members can be accessed.so here even tho the object will have some extra variables that are present in the boxweight but the reference.thatvariable won’t be able to access it as the refernce variable is of type BOX and only the BOX property present in the object will be able to be modified or accessed.
Java doesn't support multiple inheritance but it does supports multilevel inheritance so when you inherit any class that class or that class's parent class is already inheriting object class that is how every class must inherit object class.
Hello kunal I’ve doubt Should I watch the lectures in a flow for days daily an hour like that or should I stop somewhere and give a gap then practice and again start. What should I do ? I need your suggestion desperately..
33.40 Someone please check if it is right or wrong. Subclass is extending A. By default A is extending Object class. So Subclass is extending Object class implicitly (something like multilevel inheritance).

Great content, looking forward for future videos.
33:48 This is done by Multilevel inheritance and not multiple inheritance. Since the extending class has already extended the Object class.
At 33.51, a subclass inherits the properties of the Object class, not through internal multiple inheritance, but through multilevel inheritance. This means that first, class A inherits the properties of the Object class, and then the subclass inherits from class A. Therefore, all methods available in class A are also available in the subclass because of inheritance.
i'm following it consistently, helping me a lot💫✌
At 33:45 maybe we can say like
ObjectClass ----> A -----> SubClass (so basically subclass is also extending ObjectClass)?
What I understood is that every class you create is a subclass of the object class. So, yes Subclass is also a sub class of the object class.
Kunalism... New revolution...🔥

Hey Kunal, thank you for putting out quality content, especially on recursion. Can this be understood by someone from Python? I don't know Java.

Thank you ,kunal for such awesome content!!
I like the video first and then I see ur videos❤
Thanks for teaching us like no one did till now!! One small request, please make lectures on dynamic programming as well!!
agreed! dynamic programming lectures would be awesome
Never seen such an in-depth explanation before. Thanks for this amazing course.
you have not seen anything then
Thanks for your contribution. Respect!
Thank you so much Kunal
Congratulation for silver button bro
worth the time Kunal...💌

Great Explanation Sir🙇♂❤✨🙏
Good Explanation,
But just one small correction when you say it is a multiple inheritance when your extended class also extending Object class.
Actually you base class extends Object class and your sub class extends base class which extended the Object class.
This hierarchy is an example of multilevel inheritance, not multiple inheritance.
Eg-
BaseClass (extends Object)
SubClass (extends BaseClass, which, in turn, extends Object)
In love with your content. Thanks alot.
I want your hashmap tutorial Kunal😭 I love your way of teaching. If you get any spare time, please make a video on hashmap.
you are a gem of india ▄
Way better in quality than oops in 1shot videos
Thanks Kunal 👊🏻
As Always Good Content
loved it man
I m with u kunal sir
really wonderful......
Worth watching ❣️
Love the video❤❤❤
Great Content and explanation as always...

At 45:17, you're downcasting an object which can produce run-time errors. A more safe way would be to check if the obj recieved is an instance of ObjectDemo and then downcast it call num on it. I know you might have done it just to make us understand. But am i right in my conclusion.
Excellent teaching
a sub class also extends the object class because----> the parent class it is inheriting extends the object class and hence the subclass indirectly inherits the object class
Thanks a lot

So far so Good......
Minor Correction at 10:06 data member are accessible only to that 'scope' or class, not the whole file.
Great 👍
Quality Content

Great Job Kunal! I have been waiting for you to finish this course from almost 6 months. You must be very busy so can you at least recommend someone's channel so that we can move forward. Please do reply to this.
Thanks Kunal sir
Wish this was shown in java programming class instead of the boring theory that professors just talk about
Kunal's fans : Please teach us OOP ! Its very confusing !
Kunal : Hold my Beer, I got you !
Thank you...🙏
Even internally it isn't doing multiple inheritance but it is inheriting in a hierarchy i.e. SubClass extends A & A extends Object.
Now I have the knowledge of access modifiers. Love these video.
but we can aslo set the value of num which is private through constructor, How? at 9:42
Awesome video
Thank you so much bro💯💯🩷
Understood 👍

bro great content..🔥🔥🔥
Hey Kunal .. Thank you for such an amazing series .
When will we get the oops notes and how many more videos are there in oops playlist?
Java doesn't support multiple inheritance but it does supports multilevel inheritance so when you inherit any class that class or that class's parent class is already inheriting object class that is how every class must inherit object class.
Pata hai

Should I watch the lectures in a flow for days daily an hour like that or should I stop somewhere and give a gap then practice and again start. What should I do ?
I need your suggestion desperately..
cool stuff
PLEAAASSEEE Create a playlist for Java Multithreading concepts as well as Spring framework !!! 😭😭
brilliant !!!
What is the shortcut to access these methods at 34:40 ?
kunal, Please do multi threading concept. Its very important in our work place.
very simple stuff
thankkk very very thank
please create the playlist for spring framework.

Someone please check if it is right or wrong. Subclass is extending A. By default A is extending Object class. So Subclass is extending Object class implicitly (something like multilevel inheritance).
Every child class is a multi-level inheritance since it's parent(Base) class inherit properties from object(Topmost) class
