Can't imagine someone teaching all these topics in this simple way.
Amazing job sir.

[bindhushree]

None other than you could make these concepts so easy to understand. Thank you sir!

[preetamvarun]

Your lambda expressions series was incredibly insightful, and it's amazing how you've made a complex topic so accessible. Your efforts in breaking down the concepts are truly appreciated. Next on my watchlist is your Stream APIs playlist – can't wait to dive into it! Looking forward to more enlightening content. Cheers! 🙌

[raghavathogaru]

Thank you so much Pavan Sir, for making this video to understand lambda with pre-defined functional interfaces. Your way of teaching is amazing and easy to understand at any level.

[kuppusamyd]

You simplified as like Lamda!! Thanks. I will recommend your channel to my friends and colleagues.

[kiranmaiganapuram]

you made java easy to undestand which i had java phobia earlier. tq so much :)

[shankarghimire]

Wonderful demonstration and explanation!
You made Lambda so easy to understand!
Thanks for sharing your knowledge with the world!
God bless you!

Hi pavan sir,

Extremely simple way of teaching. You have an art of teaching which very few people have.
Awesome coverage.

[angelsrealestate]

Thank you so much. Just wanted to check regarding this definition 2.
Functional Interfaces: A lambda expression can only be used with a functional interface. A functional interface is an interface that contains only one abstract method. For example, Runnable, Callable, Comparator, and custom functional interfaces annotated with @FunctionalInterface. In Java 8 some pre-defined functional interfaces were introduced. There are in the java.util.function package.
o Predicate – use for conditional checks. Takes one parameter and returns a boolean
o Function – use to get a return value of any type. Takes one parameter and returns a single value of any type
o Consumer – use to pass an input but no return type. Takes one parameter but does not return anything
o Supplier – use to provide a return value but does not take an input parameter

How to use Runnable, Callable, Comparator functional interfaces? Do you have youtube videos on these topics?

[SudhakarReddyThakkolu]

Thank you so much.... Just because of your teaching i learned lambda

[kyawswarhein]

Very clear, sir. Thanks for your efforts and contributions to us

[MohammedSameer-rxrz]

God Bless you sir - your Classes are Awesome. Easy to Understand Each and Every Concept
