Yes you can....In fact if we have one method as abstract then the class needs to be defined as abstract..

Ram Kris Hi Ram, even If we don't have any abstract method in our class still we can define it as abstract. If I don't want anybody to create the object of my class then I can define it as abstract..

Good explanation !! Also one important reason why abstract class has constructor is to achieve constructor chaining. As we know the sole purpose of abstract class is to be extended. Now in any sub-class when object is created and initilized the first call under its constructor is call to super () i.e call to super class constructor and so abstract class has constructor. So if you don't keep any constructor explicitly then jvm keep one default constructor to abstract like other normal class. A constructor chaining goes till Object Class.

Anyway, because your accent wasn't that thick, I struggled through, and I'm glad I did. Yours is probably the best video on KZitem for explaining interfaces and Abstract classes. Everybody else just parrots what they've heard in other videos. Thanks again, I plan to watch more.

Interface used for two purposes in real-time projects 1)to achieve multiple inheritance (1:M) 2)to hide internal implementation And interface means you are providing user to access these methods only from implemented methods ,user cannot access non overriden method try it yourself Interface is like from one stone two birds are fallen.😅 Ok bookish right general example like TV having covering all mother board internal connection but interface on off buttons volume buttons are interface only these things using we can interfer with TV so we are hiding internal implementation showing only services (on off vol+ vol-) take other examples think on it ex(Bluetooth speaker , computer etc) So interface is nothing big topic,it means what are the things user can access that's only we can make it interface implement of that class method and make it access other methods don't implement by interface those methods are not important to access to user (like mother board user not access from TV class so don't implement it and interface reference variable can't access )or security purpose we may call ,one object(user) interface with other object interface(TV or camera etc).

No. we need an abstract class because it's not possible to create a non-static, non-final, non-public variable in an interface. plus it's not possible to create a constructor in an interface. Where we can do this all in an abstract class.

I didn't know we could declare methods with a body in an interface or variables in an interface. I have no idea about Java but in Csharp that is not allowed. In C# you only declare abstract methods, i.e method without a body. So, the only benefit is that interfaces allow multi-inheritance, which is good, while abstracts don't. But abstract classes can contain properties, non abstract methods as well as abstract methods. Is that right? Good video, thanks a lot.

Classnotofoundexception is the subclass of Exception and noclassdeffounderror is the subclass of Error.. keeping it short, the major difference is that Errors can be fatal for the program and can lead the program to abruptly stop however, the exception can be handled by the exception Handlers like try and catch.. hope this helps!!
