Thanks Sooraj that was a great and simple way to explain the purpose of abstract classes. It would be helpful if you made one video on persistent classes as well.
Thanks and it gives clear picture on abstract...i have a small doubt...If we are not planning to have implementation on abstract...only defintions...then why we need to create only definitions here... or at any time ..or on other RICEF I can just consume this abstract class definitions and play around my own logic as per my requirments with own implementation ???
What an excellent and simple way of understanding!! I was wishing you will make another sub class Cow and write "mow" in the method redefinition of make_sound 😂
Hi Sooraj, enjoyed your video. thank you. But one thing I am trying to understand is, whats the advantage of using the abstract method 'make_sound' here ? You are anyway declaring this method in subclass (with REDEFINITION). why do we need to declare it in super class as ABSTRACT method and then use it in sub class ? Can we not simply create a method in CAT class ? Am i missing something ?
Hi Sooraj, one doubt If we redefine the concrete method (sleep)of abstract class in the sub class then how can we display the original logic of parent class method sleep?
Pankaj Kumar , I saw your video, couldn't get the concept on which scenario should we use Wide cast ? Don't tell me assigning super class' instance to Sub Class' Instance is wide casing. Why should we do wide cast ? When it is needed. But Sooraj's explanation make us understand quite comfortably.

Nice 👍

or at any time ..or on other RICEF I can just consume this abstract class definitions and play around my own logic as per my requirments with own implementation ???
Awesome Sooraj !
Sooraj, please try to cover all the OOPS topics with short examples.
Very clear explanation. Please create a video on singleton class also.
NICE VIDEO PLS UPLOAD MORE VIDEOS ON OOPS CONCEPT
Session is extremely good but if you would have been explain with any example with Abap that would be grateful..😎😎😎👍🏻
What an excellent and simple way of understanding!! I was wishing you will make another sub class Cow and write "mow" in the method redefinition of make_sound 😂
😀😀😀
Thanks Suraj for your efforts.Eagerly waiting for a video on casting or on any other topic of OO ABAP.
Keep watching.. :)
It’s a good explanation thank you. Please make more videos with simple examples
Can you make video with real time scenario using sales order or something related to business . For Abstract class and methods
Love the way to teach
Thanks Ayush :-)
Please also provide odata videos
Good explain bro.. I want to join if u provide any trainings

There is a reason for that. It would be more clear when I make a part2 of the video.. Keep watching:-)
How many type of classes are there in OO ABAP?
Very helpful..... Make a video on AMDP and continue with the OOPS topic
Noted
good
Hi Sooraj, Nice explanation. Question : Can I create an Abstract class in SE24 ?
Of course..there is an instantion type drop down within se24
Hi Sooraj, one doubt
If we redefine the concrete method (sleep)of abstract class in the sub class then how can we display the original logic of parent class method sleep?
Using super_define () method.
Hi sooraj, is it possible for you to do videos on sapui5 😀
What about fish and snail?
is there a second video for abstaract class?
Hi Gordana.. not yet.. thanks for watching :-)
Please make a video on Widen cast ?
Hi Surojit, will consider that :-)
th-cam.com/video/IiakHCeCs7E/w-d-xo.html
Yes that would be great do include narrow cast as well..
