one of the most valuable programming channels in youtube . cant thank u enough. i love how he teaches. first the theory then the practical implementations
In my older Java references, they distinguish between local classes defined inside methods, but having names, from anonymous classes, static inner classes and member classes that are defined outside of any method of the containing class. But I am still watching this, it seems excellent.
I learn those features almost 10 years ago for C#, but this tutorial provides crystal clear re-brush of the concept that I don't fully understand all those years.
This is a great channel man! You are literally providing top-tier private lessons to everyone who is watching you FOR FREE! You are awesome man! Keep it up :) You are a great teacher.
Naveen Ji, I am a senior person in IT Field would like to thanks for your very easy and simple learning videos of complex topics ...Like lambda code... Thanks Once Again !!!
Hi Navin sir, your way of explaning the concept is awesom specially for lambda expression in this video. It is well understandable through your tutorials although i am new to java.
Variables i and j are, by convention, only used for indexing or iterating. This was first seen in programming back in the days of FORTRAN, where any variable named from i to n would by default be an integer, as opposed to a float. This, in turn, comes from the mathematic convention of indexing varibles with the letters i, j, k, and so on. Especially when doing summation.
I've paused the VIDEO @13:05 just to appreciate your metaphor "Creating a Class and then Creating the object is Invention". I couldn't stop my self saying "waah Sir" (KUDOS in English) :)
I am an alien, I always had my doubts but this guy said it and now I am sure I am an ALIEN!! I am stuck on earth with humans. I am learning java so that I can program my spaceship and be a free soul to roam this universe!!
Suppose there is another method in Phone interface, shall we need to give implementation for that method too?, during writing anonymous inner class code.
@@minatimahapatra4182 Lambda expression provides implementation of functional interface. An interface which has only one abstract method is called functional interface.
you have used lambda expression in an interface with single method.. but what happens when we have multiple methods in an interface.. how does the JVM undetstand that this line of code is used for specific method?
if you don't specific access modifier's than you can my sir says its not possible >>> it depends how create an inner class if they are accessible to other class..
Suppose we have more than one method i interface then how will we define those methods using lambda expression.How will it identify which method's body we have provided..?
Ok..tell me please, we know that static variables are accessed with the class name right? then, public class Other { public static class sother{ public static int i = 60; } } public class Main { public static void main(String[] args)throws IOException{ Other obj = new Other(); Other.sother ob = new Other.sother(); System.out.println(sother.i); } } What is the concept behind it, m confused, hlp me out.
Sir,if that interface contains two methods then in main method to implement those abstract methods use the method names or not because two methods how can distinguished please tell me either having more than one method you need method I think
Hello Sir, Since class B is also static. Why we need to create the instance of B also?Why can't we access variable j using B class name? Can you explain? For example A.B.j =5;
class A { Integer a=150; Integer b=150; Syso(a==b); Integer c=50; Integer d=50; Syso(c==d); } //output=false true plz give me the answer why a==b false
Lambda expressions are valid only for functional interface(Which means one abstract method), not for multiple methods. You can add a default method in interface though which will have its implementation.

Your derivation towards the lambda from the simple inner class is praise worthy ....
I feel like spamming thanks because you are such a good teacher. Your teaching style is too good and easy to grasp ❤️🙏🏻
This 22 min was the most awesome time for this day for sure
Awesome explanation
Thank you bhai
The way you are teaching ..omg really good ..mainly ur language clarity of content , your body language..super sir 👍
Super explanation sir. I don't understand Why do people dislike a video even if that video(Explanation of the concepts) is the most wonderful.
Firstly, I like the name of the channel and love your teaching style even more.God Bless You

Sir your way of explanation is too good please keep posting other tutorial for Java as I am a beginner
This man is a legend :) thanks for this tutorial
You are an extremely good teacher! Thank you for simplifying this for me!
Wonderful videos, sir. You make Java programming so much more interesting!
Awesome, no one can explain better
Literally, cant find a better explanation.
King of Java, thank you Sir
my mind blown when you reveal anonymous inner class. i never know that thing exist before lol
Amazing...
i am from Pakistan and i follow u from very long term... u r the great teacher
and Please also make some videos on Dart language
did he say "Welcome back, aliens"?
i heard it
haha, i too
he says that. He will see each coder as alien's that y he calls like that..
Harley Swift yes
He likes alien word and assume us all as variable or object notifier !
Thank you so much sir for such a good explanation.🔥🔥🔥 ✨❤️
Really good video, thanks for helping me study for my test tomorrow

You are God🙏🙏
Thank you so much for such a Phenomenal knowledge😊
Thank you, everything is excellent as usual. But can we use lambda way to cal method from inner class and not to implement interface?
thank you for the excellent demonstration of inner classes!
lamba expressions were adopted from scala.
How a wonderful explanation! Appreciate
What a man salute bhaiya 🙌🙌🙌
thanks so very much for making this video ... keep up the good work bro..
You are just awesome sir....👌👌👌
Best explanation for lambdas
we always trust you navin
your theory session is clear to me, but when i am going to run this its not works some kinds of errors i am facing
Thanks for the videos, they have helped me a lot!
Make a video on concurrenthashmap Internal Implememntation....Navin Reddy
Better to see the collections concept in " Durga soft " TH-cam channel
You are the best....................
In which case, we use inner class concept ?? Sir explain any senerio in which we create inner class...
sir, if we extend outer class in any class(take it as A) how to access inner class data members with the help of A class object??
Thank you so much for this tutorial sir.
Awesome Explanation
Found it very helpful!!!
Really like the dinosaur analogy!
Suppose there is another method in Phone interface, shall we need to give implementation for that method too?, during writing anonymous inner class code.
very clear and helpful! thanks
What if there are two methods in interface?
How can we implement the method by using lambda expression?
What if we want to implement multiple methods of interface. How can we use lambda expression for that
wonderfull video
majja a gya
why do we need inner classes?
Hello sir. If the interface has more than one abstract method can I convert the implementation into lamda expression?
i have the same doubt
@@minatimahapatra4182 Lambda expression provides implementation of functional interface. An interface which has only one abstract method is called functional interface.
you have used lambda expression in an interface with single method.. but what happens when we have multiple methods in an interface.. how does the JVM undetstand that this line of code is used for specific method?
finally I got it!! Thanks a lot
It's very very fantastic..
you are amazing at explaining
so can we acces variables of inner instance class ? my sir says its not possible :/ but i checked and it works
i too have the same doubt
sure we can, he navin should us how it works?!
if you don't specific access modifier's than you can my sir says its not possible >>> it depends how create an inner class
if they are accessible to other class..
Very clear thank you so much man
Very nice video of inner class
non static nested class are called inner class
what if there are more than one functions in the interface ? we cannot do the same implementation in the object declaration statement ? please clarify
How to instantiate static class object outside the package when the scope is default?
is staic class follow object oriented programing
What if we have two methods in interface??Then we cannot use lymbda expression?
Sir may in interface contain more than one method then who we use lamda ?????
Your doing great
great video. god bless.
Suppose we have more than one method i interface then how will we define those methods using lambda expression.How will it identify which method's body we have provided..?
Functional interface has only one undefine method.
more then one undefine method is still not valid in java8.
nice teaching method
Ok..tell me please, we know that static variables are accessed with the class name right?
then,
public class Other {
public static class sother{
public static int i = 60;
}
}
public class Main {
public static void main(String[] args)throws IOException{
Other obj = new Other();
Other.sother ob = new Other.sother();
System.out.println(sother.i);
}
}
What is the concept behind it, m confused, hlp me out.
sir how to write Lambda expression if in interface there are more than one classes are declared ?
Weird is his one of the favourite words.
I know that’s weird 😬
How to access static variable within static inner class??
Sir,if that interface contains two methods then in main method to implement those abstract methods use the method names or not because two methods how can distinguished please tell me either having more than one method you need method I think
That means which code belongs to which method, you have to specify that ...
Hello Sir, Since class B is also static. Why we need to create the instance of B also?Why can't we access variable j using B class name? Can you explain? For example A.B.j =5;
No, Since the inner class variable j is a instance variable, we have to create object to access that variable. If j was static, then A.B.j = 5 works.
While watching java videos on my phone why it rotates 360° ?
Can't we access member inner class variables without having variables in outer class?
If it's static class so how can you create it's object?
hey hi sir do you have courses in udmey
I want to know does static inner classes are also loaded in computer's memory at the same time a normal static class would or it behaves differently.
excellent sir👍
I think the Lamda example is confusing because you didn't actually show how to call the lambda function, p.show().
Thanks for making this video :)
what if interface has multiple methods??
class A
{
Integer a=150;
Integer b=150;
Syso(a==b);
Integer c=50;
Integer d=50;
Syso(c==d);
}
//output=false
true
plz give me the answer why a==b false
wonderful things learn today....thank U so much aliens. ;)
great video sir
What if the phone interface has more than one function, then in lambda expression how we know which function is calling.
He forgot to mention. It must have only one method, otherwise you can't use lambda to instantiate the object
Sir!!!!!!What is method local inner class????
Sir what happen if two or more methods are there in phone interface ,then can we use lamda expression????
Telusko Learnings So sir it is only for that interface which having only one method ?
How do I create an Inner Class of a class with the same name?
Simply good
sir what happened if interface contains more then one method then how to redefine one particular method with Lemda Expression ??
Lambda expressions are valid only for functional interface(Which means one abstract method), not for multiple methods. You can add a default method in interface though which will have its implementation.
