An abstract class is an incomplete class. An abstract class is defined with the
keyword abstract . We cannot create an object of the abstract class because it is
not complete.
These classes cannot be instantiated and are either partially implemented or not at
all
implemented.
This class contains one or more abstract methods which are simply method
declarations without a body.
This class is used when common features are shared by all object.

superb!
sir likes phones….. 🙂
Nice video. With good presentation
welcome aliens lolz
sir it is compulsory to have one abstract method in a abstract class
Sir why to make a object of abstract class as we can use the object of child class …why referencing????
great..
Well done ! Keep on ….
I get confused
thank you
Very confusing. I almost understood nothing! Some videos are very good but this one with those confusing names , Ramesh, etc. made me confused.
thank you bro.
Hi, Navin.
Thanks for the explanation. But I have a doubt here. Please help to understand.
When you want to add some new features, you can do it by inheritance concept, right ? Why do we even go for "abstract" ? Because, in your above example, "iphone extends phone" and "Samsung extends phone" could have been done without abstract, right ?
thank you very much for the tutorial. Was really useful to understand the abstract class and methods
subscribe in the top right corner is annoying…
8: 17
Show (new phone()) ;
The new feature of a phone, to cook like a microwave it's really funny …….
What can be the characteristic of private static inner class having private methods….?
really love to see your tutorials, always helpful, thank you 👌👌👌🙂🙂🙂🙂
i want the phone which acts like microwave tho hahaha what an example
8:13
The exact moment my mind was blown
i think this example is much easier for indian students. names are confusing. and sub icon obscures the examples
Can abstract data members be created??
i have one doubt even a single method is abstract so its compulsory to make whole class abstract .
Amazing Explanation………………
start==super;
finish==super;
In abstract class program is it compulsory to import any package??
Excellent explanation.
Big Thumps Up from me.
Instead of Suresh Ramesh confusion, could have done with A, B and C which clicks quickly to a user.
Where to use abstract class and where to use interface ? Apart from that multiple inheritance not support it we extend abstract class … Is there any another reason
Absolutely hilarious requirements description, but conceptually it is spot on.
very good.
I appreciate your work
great explanation !!
on my netbeans, i need to input abstract in every sub class or else it will count as error. is that normal?
Thank you so much. Keep it up and help us(:
Very nice teacher!!!
Sir I still don't understand what is the diff b/w inheritance and abstract. Where do we use abstract and where do we use inheritance
I like ur explanation sir.😃…..and …some times it makes me confuse .😮..
sir u said we can not create object of abstract class! and then u are creating object of abstract phone class in parameters!!! why??
Sir If there Is a Base Class A and B extends A and there is another class C which extends B So the Methods in A will also be presented in C?
sir ye mahesh , ramesh ko kya zaroorat hai itne methods declare karne ki , jab unka code nahi bana sake ….bechare suresh ko virasat main ye abstract means aadhe adhoore methods hi mile …wo ek paper main hi likh leta na , class main likhne se kya ho raha tha ..bevkoof
nice u are asking us to share on our channel or what?its not a rught thing to do right?
Thank you so much sir, nice explanation……..no words to say, its awesome
Thank you sir. Excellent explanation.
sir @.7.52 in left hand side it says show(new Iphone()) ; what this measn? creating an object ? I create object like this iphone obj =new iphone(); In static show method in the top left there a parameter iphone obj whats that?
