Difference between Interface and Absract Class

[@donamathew1749]

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....

[@hareeshjp]

same with me.

[@jabariterrence4539]

I know im asking the wrong place but does anyone know of a tool to get back into an instagram account..? I was stupid lost my password. I appreciate any tips you can give me!

[@oludamilareolukotun1783]

I have never see any any explanation as clear and co concise as this. you are a great teacher

[@truthlover3522]

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.

[@sureshm2047]

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

[@venkateshandea1767]

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]

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)

[@spsingh4297]

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

[@maheshappala3150]

The way of teaching is excellent naveen .i am new to java but i am understanding quickly and i am also watching your selenium videos.Your voice is very clean without any disturbance.thanks naveen for uploading videos

[@sanghamitrabhowmicklive3013]

I don't even know how to thank you. The way you explain concepts, I don't think I have ever seen someone like you. Hats off to you!!

[@naveenautomationlabs]

Thanks for watching :)

[@apoorvabhavsar1645]

Awesome videos, I have learned it around 8-9 years ago as a theory but this video made the idea crystal clear. Just love your teaching abilities. Keep it up and huge thanks for all your videos.

[@naveenautomationlabs]

Thanks for watching

[@sathiyaasothana9905]

You are doing great man really don't stop this many of them are getting their career with your help...Their is no words to explain and thanks for all you efforts

[@kaushikyadav5284]

Now i can not forget difference between this 2 topics thanks Naveen

[@oshadigodage29]

Best explanation so far about the abstract class and interface, Thank you Sir

[@RajuSingh-lt8cd]

I dint know anything about java yesterday.Now ,it seems I know almost everything with concept in one day. Excellent Naveen sir.Benefit ratio is 100% in one day. Best tutorial found on 1st day of my java learning. Thanks.

[@naveenautomationlabs]

Thanks for watching. Keep learning

[@vikrampatil1340]

Very nice video with clean and clear explanation. At first I thought it is very long but after watching it completely, I understood that 30 mins are actually required in clarifying the concept. Thanks Naveen. I really like your videos and I am going to recommend it to my friends as well :) Keep up the great work. Love from NZ

[@ankitkhusabu]

One of the best vedio on interface and abstract ever watched

[@faizanhussain1879]

Great .... I take the java concept to fulfill my PHP work ..Thanks for the explanation sir

[@user-kz7sf5dz5v]

I am new to learn Java. I was so much confused understanding difference between interface and abstract class thanks Naveen you cleared my confusion. Really appreciate your honesty in sharing knowledge. By the I new to your channel as well. I need help with Array if can help me or share the link if already have a video on.

[@Sandeep11067]

You made build interest in Coding stuff, Otherwise i didnt have much interest towards Programming, Now i am Loving this. Thanks.

[@deepakrai5175]

most simple and clear video of Abstact classes and interfaces. Thanks !!

[@naveenautomationlabs]

Glad you liked it

[@anithachimbili105]

Hi Naveen, I wanted to learn selenium with Java, kindly let me whether you are giving training, Also let me know if you r teaching realtime

[@naveenautomationlabs]

yes refer this : naveenautomationlabs.com/selenium-training/

[@devimedisetti9317]

Clean and understandable explanation, thank you Naveen

[@hemlatamehra7409]

excellent video naveen...could you please provide soft copy for all java interview Qu and ans.

[@papridutta2336]

Thank you Naveen for explaining so well the concepts of Interface and Abstract class.You are gem

[@wolfgangbenfattoum8137]

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.

[@achaljain15]

Thanks, Naveen for such amazing videos which are clearing almost all my doubts, As soon as the question pops in my mind, You explain it the very next minute in the video. Great teaching skills. I hope, I recall all of it well in my interviews! :)

[@manimaranvaradharajan4073]

Its Very Cleared about Interface and Abstract. Thanks Buddy.

[@sandhiya7781]

Great explanation ...reallly osam

[@sakshiranu]

Excellent teaching, Be my Mentor Naveen🙏

[@RaviKumar-lc3bf]

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

[@sacsp1]

Thanks Naveen for explaining it in easy way. I have one question here, can we create object of abstract class using anonymous class for overriding abstract methods of abstract class then using same object to call other non abstract methods.

[@abhilashadeshpande7996]

Thank you naveen.. your videos are always life saver for me.. I have a question, can u pls tell me which is the abstract class in the selenium library.. ?? In every interview i am getting this question..

[@indrajitbhattacharjee8204]

nice explanation just a suggestion can add an example from selenium perspective

[@bhagyashreeulhe3232]

Thanks sir..very informative video ...this question was asked in interview

[@bedaradurugaiah494]

Excellent concept was explained by Naveen super

[@venthangowthamsivakumar5510]

Awesome explanation Naveen

[@mohammeduneab8991]

Awesome your videos are helping alot..your way of explanation is really nice and gives a clear understanding

[@mariabajwa8632]

thankyou , its amazing ,all concepts are crystal clear.

[@khushbooraikwar8210]

One of the best video, Thankyou Naveen!

[@abhilashmt6161]

what about the static and default methods in the interfaces, which are non abstract methods right?

[@grvlal]

Thank you Naveen for sharing the knowledgeable video.

[@AlanVargheseAniyan]

Does an interface achieve complete abstraction even after Java 8 where default methods are introduced?

[@traghavendra9828]

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

[@harishpandey3267]

Superb Explanation.....thanks a lot Naveen

[@lokeshbisht438]

Perfect way to understand abstraction and interface. Really enjoying your videos.

[@chandankorde3544]

Thanks a lot Naveen sir ....clearly understood the concepts..pls make sure It will be available to us always... thank u so much sir..

[@neelimacse2012]

thanks for the video..its very useful to know the diff btn both....

[@vidulabhat]

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]

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.

[@karthikmurale]

Thanks Naveen .. i am searching for this topic in your videos

[@manishpatidar5379]

perfect explanation as usual.. Thanks

[@myamazingvideos]

Hi Naveen, I am going through your courses and finding them to be very carefully woven for better and thorough understanding of the viewer. Hats off for that. Having said that, could you please answer a doubt I have ? Can a non-abstract class have an abstract method as well ? Thanks in advance :-)

[@elinamdoraashley882]

Good! was really struggling with the difference btn Abstract class and Interface....Thanks soo much for this video

[@sundramyadav5934]

Difference between abstract class and interface, when to use them, and how to define abstract class and abstract method. ✦ The main difference between abstract class and interface is that abstract class can have both concrete and abstract methods, whereas interface can only have abstract methods. 00:05 ✦ Abstract classes allow the creation of multiple abstract methods as well as non-abstract methods. 02:41 ✦ Method overriding and abstraction concept 07:47 ✦ Abstraction is a way to hide implementation logic 10:13 ✦ Interface allows defining only abstract methods. 15:50 ✦ Implementing 100% abstraction in Java 18:32 ✦ Accessing overridden methods and non-overridden methods in BMW class 23:24 ✦ BMW does not allow parent reference variable to access specific methods 25:57 ✦ The basic difference between abstraction and interface 30:05

[@pradyumnnasatapathy8199]

Thanks a lot Naveen sir for this detailed information

[@vasavirayapati8876]

5* for your teaching ability. do we have any latest video with java 8,9 features. If any please share the link

[@amanueltesfu6071]

Excellent explanation. Thanks Naveen!

[@9chainsgtr]

Thanks man! Your help is great!

[@vinaysharma530]

Sir you have much depth knowledge about concept 💯👌👌🙏

[@Harsh_H_Patil]

Thank you sir really clean and clear explanation. Please can you upload one video on java 8 when to use abstract c and interface bcoz in interface they added static and default method

[@yashovardhangoyal9270]

Thanks Naveen!!! Very Well explained

[@vinoddhale2428]

Thanks sir for clearing my concepts..😊😊🙏

[@akshaysingh5179]

Very nicely explained.Thanks for this video.

[@truthlover3522]

Great Navin, i like your videos , awesomely explained

[@lisazhou7776]

very simple and cleat to explained the concepts. thanks.

[@waniya-huzzu]

Can you give any framework related example where we can utilize this abstract or interface concept while designing framework

[@devinealmighty001]

Take an example of webdriver and chromedriver Web driver is an interface and chromedriver is a class which implements webdriver interface... Hope this helps

[@itsrohittiwari]

You did not mention about default methods of interface introduced in Java 8. Please mention about it.

[@RajuSingh-lt8cd]

Excellent Naveen..Hi,Can u pls provide videos on (Cucumber+Protractor+Typescript+Visual Studio Code).It will be helpful. Thanks.

[@A_philodendron]

Hi navin, Can you please make vedios on c#? Or suggest any vedios which has good explanation like your vedios?

[@doodsmix4015]

best tutorial so far

[@naveenautomationlabs]

Glad that it helped you..

[@sindhusudhakaran1731]

Thank you Naveen. This is so helpful !!

[@ComputerTechnologiesLab]

Superb Explanation..👍

[@mohammedzakaria8783]

Thank you for such amazing work, Naveen, can u pls dicuss the difference after java 8, I heard there is a big change. Thanks in advance

[@mitthuanjali1823]

Superb informative 👌

[@RajuDas-zn3gx]

Can parameter be given in the parent class for both abstract class and interface?

[@nehaverma-dp5mm]

Superb content!

[@ashoktheja3346]

Sir can multiple inheritance done for abstract class ?

[@santhoshsomaiah]

Very good explanation

[@Driverforcash]

Very nice video Naveen Sir !

[@vatsalraj2655]

Very nice and clear explanation

[@MrAmarSindol]

Excellent bro, thanks

[@anandkumar-qj2zw]

why is it that we can't create abstract classes without any abstract methods ? I did not got any errors while doing so..

[@sureshm2047]

Really Naveen tutorial the great stuff tutorial... thanks a lot Naveen

[@kalyanimeshram7669]

Just awesome 👌 👏

[@madhum3307]

Thank you so much for efforts Sir..!!

[@maronnambo7918]

That was very helpful. Thanks.

[@sreenathreddy2791]

i think with out abstract method also we can define abstract class. there is no restriction on that. Can you check that

[@rahuljain3547]

Very good explain 👍

[@MihaiKoteles]

Good presentation but still this doesn't explain what are the benefits using Interface during code design when in which use cases to use Interfaces to avoid tight dependency coupling, can you maybe create a video to explain interfaces and their usages in respect to SOLID or code design in general, to answer more the question WHY do we need this, what benefits do they bring, etc.

[@shilpakhot6977]

plz make the video on abstract class and concrete class

[@indraparmar8666]

Interface can have only abstract methods. Since Java 8, it can have default and static methods also.

[@navnathjadhav9111]

In Java interface can also have private methods

[@sureshsubramaniyan3201]

Simply superb

[@ishwaripednekar5164]

It's not necessary to have at least one method abstract in abstract class. But if there is exist any one method abstract class must be abstract.

[@rajeshdhonde9256]

Very nice Teaching

[@Abhishekyadav-xd2ib]

We can say concrete method too to non abstract method ?

[@saravanabalaji3121]

upload image comparison using Assert in selenium Java -TestNG (hybrid driven framework).

[@prajwalprabhu7109]

@naveen is it necessary for a class to have at least one abstract method to make a class as abstract

[@agitay272]

Great explanation brother

[@manojpatil2457]

Just one correction we do not need to have at least on abstract method to make a class abstract . Rest I always like your videos .

[@webster.]

Java 8 default methods in interface is a killer
