I am trying to learn Java for the longest time. Never got the concepts clear. You have been a life saver for me. I don't feel the need for any other tutorial now. The way you teach is the most perfect I have seen. Thanks a Ton!!! Please continue this great work....

Even many Java experienced guys find it difficult to explain difference between interface and abstract class, they just keep on reiterating interface and java but miss the clean explanation, but the way you explain with such a clarity , WOW., first time ever seen such convincing explaination.

I have been watching since 3 yrs about abstract and interface but no one has given clear cut and didn't understand but first time my doubts gone by watching this extraordinary video

Excellent explanation for guy like me who is a beginner, Plus Naveen's accent is very Neutral and not like other people videos who says yeight to 8. Wish you billion subscribers

@venkateshandea1767 6 жыл бұрын

Hey naveen ...i really appreciate your work...one requenst from my side make a video on ....where we use all these concepts in selenium....i.e abstraction, polymorphism, overriding, overloading, encapsulation ...etc...thanks

@deeepzzz Жыл бұрын

It's the same. You just need to learn java and oops concepts and you can work in selenium (or even in any oop programming language once you learned it well). (I know it's late answer, but may be useful for others)

excellent video. most demonstrations regards interfaces lack precise explanations. I took me a long time to grasp as well. What needs to be shown is what happens at the dot operator when using either an interface as refernece type or the class as reference type. that way you can see what methods are available as soon you press the dot. cool stuff.

Hai naveen .. I like your classes very much. In the interview for QA they are asking how interface and abstract use in selenium. This type of questions are little hard to reply. can you please tell us OOps concepts and also where OOPs will use in selenium

Hi Naveen, Can u provide me where we use interface and abstract class in any project with example

@vidulabhat 4 жыл бұрын

Thanks Naveen. Amazing clarity I got. Just have one query.. if all the methods in an abstract class are abstract, does it perform better than interface? If yes, what is the use of interface...as abstract class is achieving the same thing with better performance. Does interface do anything, which abstract class cannot do?

@aniruddhvale 4 жыл бұрын

i think a class can implement multiple interfaces but it cannot extend more than one abstract class. It cannot do multiple inheritance with Abstract class. So this might be the difference.
