#65 What is Interface in Java

[@DeeperRed-of1gp]

At 7:26 it is said that "we are doing implement not extends so only methods are available and variables are not available". Actually, regardless of what we do implementation of interface or extends of parent class, the variables also gets passed on in child. When we do Subclass obj = new Subclass(); we can see that variables are accessible. The thing with interface is that as the variables are final, so we can't change it. But it is available in child class! Maybe it was just Slip of tongue by Telusko! Enjoying the series so much! Thank you for posting it!❤

Actually according to GPT , In Java, static fields declared in interfaces are accessible through the implementing class, not inherited. When we access B.age in above example in main method, it's not due to inheritance, but rather because interface fields are implicitly public, static, and final. In our case, age is a static field of the A interface, which means it can be accessed using the interface name itself (A.age) or through any class that implements the interface (B.age). So, while it may seem like the field is inherited, it's actually being accessed through the interface. This behavior allows for constants and other shared data to be accessed consistently through the interface, regardless of the implementing class.

Your Process of explaining and the step by step developed example is just blowing my minds. Tomorrow is my java final exam. I have regrate that why I didn't follow you from before! Your teaching system is well pre-planed, clear. I have a request, plz don't stop making tutorial. Keep doing by this way of explaining. Need Python ,framework, Algorithm from you.

Today I subscribed you after watching this video. Your explanation and English pronouncing are better than others. I respect you my new Teacher ❤. Love from Sri Lanka

Great playlist! There are some other videos in this course playlist that explain the terms used in this one. Feel free to give them a look if you're in need of a quick refresh! - Abstract and Anonymous class: kzbin.info/www/bejne/aorReHWFrqZlh5Y - Static Variable: kzbin.info/www/bejne/bXm8koSFrtuqbbM - Static variable Example: kzbin.info/www/bejne/bXm8koSFrtuqbbM - Heap: kzbin.info/www/bejne/lXiuZIqle6t-i6c - Heap memory: kzbin.info/www/bejne/mYeQpIKmhMyinJo

I have been watching Navin sirs old vedios and found this gem ....good to know you are doing well....looking fresh sir ✨ with an upgrade

[@daulitech219]

I read Interface through a book but I couldn't understand it, until I found your video. Thanks

[@Arsun-77]

[@projyoti7489]

What a type of teaching skills ! Mind-blowing

[@mangaraj45]

That's not my age 💀🌚😅

[@mohitx3g]

Bro's age is 43, and he written 44 😂

[@iqbalsingh3848]

your video just blow my mind.. its crazy ... thanks for a lot of information...

[@AmarGrg]

Hi @Telusko thank you very much for all those wonderful videos. Just started learning java and I am already learning alot. Have a quick question for you, while doing PHP we used to write interfaces for the model entity class, what do you think about it? what might be the pros and cons?

[@adityasrinivas3069]

Video #66. and #65 should be interchanged, i.e, explain what is an interface and then explain why it is important. It will be easier to understand.

[@Telusko]

Thanks for the correction

[@raghavsood768]

Notes: All variables inside interface are static and final

[@mohamedmurshid9794]

and public by default too. all the methods inside interface are public and abstract.

[@mehakfatima6531]

​@@mohamedmurshid9794 well they have to be public so that the abstract methods inside it can be used further in derived classes or the whole point of creating a interface will be nothing

[@mohamedmurshid9794]

@@mehakfatima6531 yep true. But i just added those are public too. Not only static and final. Thank you for this comment.🤗

[@alwinvj6487]

Thanks for this video🤗

[@VishnuSai-u2e]

Without out main() we can i print any statement?

[@sriemandi3978]

Merry Christmas Naveen bro

[@Programing-lo3og]

Thanks You Sir

[@adityamishra_11]

Are we take scanner (input) at the time of declaring any variables inside the interface.?

[@adityamishra_11]

@Telusko.

[@roshanekka8293]

nice explanation

[@manas332]

Excellent explanation

[@Hemanth83439]

kollada mona 👌

[@srimantamondal8769]

Can someone tell me why inside println(), "x:" is used. This variable "x" is not declared anywhere and is not giving any error. Also if it is not a variable then let me know what it is.

[@santhosh-benz7]

Here inside the println(), "x:" is used , it is provided by the IDE ( here VS code ) , which means it remains you to code here or pass the parameter , which makes you aware about the line of code . It needs some thing based on the code . I think you can Understand 😅

[@shubhrajit2117]

You can disable it by going to settings -> Java hints -> None

[@chouaibakni2828]

Thanks

[@rohitgundam2275]

How is he able to create an object A (since this has the same name as the interface?)

[@edgbaston149]

Thank you so much

[@sheikhnasir3437]

6:13 Funniest part 😂

[@Ambitious675]

Thank you so much sir :)

[@Nothingtosaymore]

Thank you

[@filmbuzz9419]

Can i implement another method in class B

[@sushmithakn6003]

Why this error come - failed to resolve main method code lens :inter faceis not a valid java identifier
