not suppose to be but great! 😄

Anthe antav aithe 👍

In right hand side , ie the obj side, since you have Abc() which refers to a new class address(as we know the purpose of this is to create an anonymous class which is automatically used to implement the interface which is used as reference). So interface and class are 2 diff things here and can have the same name . Thanks !

equals is the method of Object class

I have the same question. I want to see some use case for a functional interface..

you cannot create object of interface

no you cannot make multiple method interface to lambda expression. Exactly one method is allowed

Even i wonder...

it is a object of annonymous inner class not interface

@Dr Pi k

basically you have a new object in memory which defines method show() (defines - gives body //gives curly brackets {}) through the help of lambda expressions

we can not create an instance for an interface

instance varible of interface is public static final by default , by default method inside interface are in public abstract ...

suppose an wenhave interface A{ void Help(int a, intb); } this is also a fuctional interface.

Imao just google it..

interface A{ void Help(); } abstract class B implements A{ public abstract void keep(); } public class InterfaceImplementByAbstract extends B{ @Override public void Help() { // TODO Auto-generated method stub } @Override public void keep() { // TODO Auto-generated method stub } public static void main(String []args) { } } yes

In Interface, Implements keyword must be used only when we have to extend something from the parent interface to the child interface...Here, in this video there is only one interface in the program. So there is no way to use implement keyword here... And even when we create an another interface and make that interface to implement from the above interface. The child interface's only job is to override the parent interface... Instead we can create an anonymous class and do the same job to make the code more efficient.. Guess!!! I'm right with the explanation.

We don't need functional interface... If a interface has just one method in it, we simply call it as functional interface..That's it

Functional Interfaces are mainly used in Lambda expressions, Method reference and constructor references. In functional programming, code can be treated as data. For this purpose Lambda expressions are introduced. They can be used to pass a block of code to another method or object.

it is sake for programmer, if you want you method definition only upto to particular class . then use functional interface concept.

Maybe try putting brackets around the sout statement?

for sake of programmer to use anywher easily.

yes

The object is not created there Instead it is an syntax of Java we call it an annonymous inner class we can implement the method in an easy way rather than first creating class which implements An interface than creating an object for it and using it

if Abc is an interface you cannot create object of Abc . but you can implement Abc and create reference variable of Abc type

if Abc is an interface you cannot create object of Abc . but you can implement Abc and create reference variable of Abc type

😂🤣

yes it is most similar to javascript arrow function. and in java it is known as lambda expression or functional interface.

yes this is allowed ... here we define body of default method and hence it work like same.

it is not better for everyone in term of readibilty. But it is easy to use if you know.
