[@abhikamboj4152]

5:36 race3 dialogues were originated after watching this video....hit like if you are watching this video in 2k18

[@RiteshKumar-ri1xq]

[@deepthisindhuri7392]

Thank you very much sir..... (Y) Great job.....

[@saiyyedkhhizraalam738]

Sir giving examples of s3 and samsung literally planning on rolling out s12

[@shuvshaw9594]

very helpful

[@rohithreddy8516]

You are calling add() method from class A to class MainClass before doing inheritance,is that mandatory that you still calling add() method after inheritance?

[@mohammedviso2269]

Great Video

[@bnv9464]

You are simply great, Best Explanation I ever heard. Thanks:).

[@md.aminurrahman2352]

please details about multi-level inheritance

[@himanshusharma5267]

awsm sir

[@blacktenshu]

Thank you for simplifying the inheritance concept. It helped me a lot in my studies. I'm currently majoring in Computer Information Systems.

[@huznmeee]

Check out thenewboston. It is because of him and Navin Skills that I have finally grasped the concept of programming. Repeat everything until your brain hurts, and you will never forget Java.

[@harikishan1746]

super.. thank you

[@varunraj9079]

u have created a class A and class B and at last we created a main class where we wrote obj.B=new B(); later u wrote obj.add; and my doubt is what if we write {obj.A=newA(); obj.sub;} or {obj.B=newB(); obj.add(); obj.sub();}

[@eswar2294]

oh my god, if he starts attending interviews he would literally get an offer from almost all the companies.

[@kavinduvindikasomadasa352]

For an already existing app(assume it is created without using any sophisticated frameworks), creating a newer mid layer *class B* and extends class A possible to make a difficulty of changing all the class A implementation(that we previously had in our application) to class B right?

[@hadisyadollahi7112]

what a great Explanation! you are such a great teacher! thank you for sharing these videos:)

[@gatlarajesh3588]

thanq you very much for providing us such a great lectures in java. we all be waiting for your upcoming lessons on java

[@prashanthgone7369]

Sir why we dont have hierarchical inheritance

[@akashstark1836]

There is one more inheritance called hierarchical inheritance... Two child classes extends one base classes Ex : class A Class b extends a Class c extends a

[@gopalsharma2195]

extremely smooth explanation , thanks very much for this sir !

[@shuvodeepdas1991]

what about the hierarchical inheritance????

[@sivadasari9647]

Very good

[@samanfarid3699]

one of the best teachers i've had thank you :)

[@sanjupole1491]

why in class A, another method sum() can not add /make the changes in A class ?

[@abnormalbat1966]

U R AWESOME !!!! thats one thing I wanna say :)

[@zubairmujeeb8455]

It is a mechanism where sub class inherits the features of their parent class by using a keyword called extends. Different types are as follows: 1- Single Inheritance 2- Multi-Level Inheritance 3- Multiple inheritance. Note: Multiple Inheritance not allowed.

[@edwininfant860]

u ve done a great job man....continue ur gud wrk !!!

[@KhangariGaming]

I am Alex .. I am a Bangladeshi student who is studying at Canada .. To be honest your lesson are easy to get and you teach better then my phd professor ... thank you

[@anilrautela5260]

I started watching your videos from 2020 and this current video is watching in 2022, I want to say, you really made a great effort and hard work to reach there. Kudos!!

[@LukaszSkyWalker]

Thx!!

[@mamtarani8331]

But sir where is hybrid inheritance?????

[@prajaktajagtap8699]

Can we determine size of class?? And if Yes then How??Whether sz of subclass will be greater than super class??

[@hamdamboyurunov6034]

Nice explanation, I assume that your math base is fine, so your explanation more close to others. Graphical method to teach to other so pretty well

[@madhushreesalimath8498]

teaching is best and illustrating with simple ,easy examples make the person to understand in better way ..thank u

[@mollasakil694]

Ohhhhh hoooo you aree genius mann✌🏻 Happy to have youuuu

[@madhubabu3840]

y multiple inheritance is not supported in java plz explain in other video of ur

[@farooqsyed9966]

We have more 2 types

[@ΑντρέαςΣωτηρίου-π8γ]

f i want to call both the super and this constructor is it possible?

[@austingrant7060]

Thank you so much for explaining Inheritance :D it helped so much!!

[@mangeshkadam6707]

which of the reference book specified by you in the description should i buy ??

[@korlamskrishna]

Wonderful Explanation on the concept. thanks for the video.

[@brocklesnar8132]

so abstract class is parent class???

[@chetangautam95]

thanks for this video...🇳🇪🇳🇪🇳🇪🇳🇪🇳🇪🇳🇪🇳🇪🇳🇪🇳🇪

[@saisidharth96]

my dad's phone isn't my phone man! :P

[@i_karank]

u done with ur lame joke? :p

[@abhisheks1036]

Then he might not your dad..!

[@rukiyaomar477]

is there anything like hierarchical inheritance where several child classes inherit one parent class.

[@rishinikumbh]

nice lecture help to clear my basic doubt.....

[@gouthamkumar102]

can you pls come to our college and take spl classes

[@bhaskarsingh893]

isn't multiple same as hierarchical inheritance

[@alishanali4340]

you can make a baby understand basic java..

[@neerajag5249]

in main function can we write obj.sub () sir

[@stuntman07055]

very good video

[@rajramsahoo6931]

u have no idea how much u r motivating ppl

[@RajaKumar-nl1pt]

Wow! You made this clear to me. Thank You

[@shraddhapawar5674]

This man is to good ,thank you sir.

[@wyattanderson5169]

nice explenation keep up the good work!

[@mohamedthoufiqm8108]

❤️

[@urScorpioLady]

well explained. Thank you.

[@daniyaljavaid329]

dog barking was irritating btw :p

[@nirmalrevar]

well explained.. liked it

[@RehanRehhu]

Thankyou Sir :)

[@jayashree9747]

how many classes can be extended in java?

[@daniyaljavaid329]

multilevel inheritance can be done several times, there is no limit, but multiple inheritance is not supported in java

[@MrRahulskumar]

Multiple inheritance can be done by using interfaces. Example: If we need to use Threads, we can use it by extending thread class. If we are already extending a class and need to use Thread, then we cannot extend Thread class along with that class. In such case, we can implement Runnable interface. Valid: public class Test extends Main implements Runnable{ } ---- invalid: public class Test extends Main, Thread{ }

[@sidharthk.burnwal2044]

nicely done ...

[@chinnababunaidu]

excellent sir

[@pratyushsingh3967]

nice nice nice

[@alishanali4340]

love you bro

[@diroshratna2663]

Awesome

[@Sanjeev.Network]

Awesome

[@ahamedaaqib2590]

Awesome !

[@pritilipipanda9540]

I have a doubt. Why we need class main class

[@mam8800]

Pritilipi Panda, With out a main class a program cannot run. Its the entry point for a program.

[@rohinkumarkumili5271]

[@daniaalghamdi204]

3 years later and it still helps, thank you

[@siddharthamyakala8961]

7 years later and it still helps

[@brianlaudrupchannel]

Why cant you just add more methods to class A even if someone else created that class?

[@joefyneface4525]

+billyblackburn87 Look at each class as a template. One could add methods to class A, but then the template wouldn't be what the original class A was meant to be. However, by using inheritance, you can draw all the methods from the original template (class A, or superclass) plus methods specific to the subclass (class B in this case).

[@brianlaudrupchannel]

I understand. What I mean is whats wrong with changing class A so its different to the original? Why does class A have to remain in its original form?

[@joefyneface4525]

+billyblackburn87 You could jam all your functions in one class, but doing so could lead to confusion , maybe not for this example, but imagine this. What if you had designs for several different cell phones, 5 cellphones for example, each with the same core functionality? Changing all the methods in one class to reflect all the other phones can be messy. Instead, it would be wiser to create a superclass for core functionality (1 superclass) then extend the core functionalities to each of the subclasses (5 subclasses representing the different cellphone) where you could create methods specific to those cellphones. That way, if a problem arises, debugging is easier. It makes code more modular.

[@brianlaudrupchannel]

Joe Fyneface ok I get ya now

[@joefyneface4525]

+billyblackburn87 Awesome xD

[@abhaychaturvedi409]

I didn't understand anything
