This the best tutorial on Lambda expression.I have seen lots and lots other videos and getting more confused.Thank you so so much Sir.

[@salmanbaig7746]

Basant you are a genius who is not only kind hearted but very thorough and expert in technology. Thank you Sir.

[@RahulThakur-jl7pm]

Best video for Java 8, I had cleared my interview based on this video. Thank you so much.

[@Javatechie]

Waoo first of all congrats Rahul , glad to hear this

[@sujithg5873]

Many videos I seened but I didn't get any idea using lambda.But now I got the idea.Thanks broi

4:00 Interface methods are by default abstract and public. "abstract" keyword is a non-access modifier. abstract keyword is used as prefix to classes and methods. Abstract class cannot be used to create objects and it can be accessed indirectly after being inherited from another class. Abstract method does not have a body. And it resides only in an abstract class. Also, it is possible that abstract class can have non-abstract methods as well as abstract methods. Interface attributes are by default public, static and final

Fantastic....Boss....I have been working on java 8 from last one year but didn't use Lambda but yes used Other classes also like stream filter etc... Please make videos on Stream API using same style of explanation i.e with example. God bless you Boss.

Series continuing sir

[@gautam7452]

Super Basant :)

[@tomaspyth7017]

Thanks a lot for your awesome video. My understanding for that was always that lambda function is actually an Object of an *anonymous Class* that is implementing the functional interface and not a anonymous function! It isn't!??

Thank you sir!

Sir first of all heartily thank u for providing and sharing ur knowledge. We really want these types of examples as these things help in real time projects.

Great explanation but that lambda method in the end for sort will not work if getName is null ? How to handle that and keep our code small also ?

Yes before lambda you should know functional interface

Sir ..why functional interfaces are restricted to one abstract method?

[@raghuakuthota4900]

hi techies, I am sure, Comparator will have 2 methods - compare and equals - here, still, can we call it as Functional Interface is it?

[@Javatechie]

Yes equals method override from object class

@@Javatechie - yeah, even I felt the same - thank you for clarification

[@bharatmakkar9706]

Just an advise. Avoid using concepts like DAO etc. as the person watching the video may not know about such design patterns if he is a newbie to the Java world. Otherwise, the video was good.

[@Javatechie]

Yes got you thanks for suggestion

For me it's a gem to get the deep understanding on functional interfaces

i seen that, i think u thought to do another video on vm profile. that one is helpful bro. thank u

[@akashtawade9264]

But comparator has 2 methods, one is compare() and second is equals().

[@Javatechie]

Equals method is default one not abstract method
