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.

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?

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.

when we create interface. In interface all methods are 'public abstract' by default. So, no need to write public abstract. we need to define those methods in the class. Otherwise that class will become abstract. Again we need to creat concrete class and define methods. In the interface, we can decleare varibles but those variable will be final and static. So, we have to define those variables like int age=32; String area="Mumbai". Interface don't have memories in the heap. we are doing implements(class implements interface) so we implements only methods NOT variables. As interface don't have memory how can we create non-final or non-static variables in the main class so, we can not be able to change variables ' values.

Notes: All variables inside interface are static and final

@mohamedmurshid9794 Жыл бұрын

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

@mehakfatima6531 Жыл бұрын

@@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

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 Жыл бұрын

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 😅

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