Hi Durgesh Sir, I am Rajojyoti from West Bengal. I am Software Engineer @ CTS but learnt many things from you. I always follow your videos and ask others to follow too. Thank you very much for your wonderful initiative
Hi sir, I am from Nagpur Maharashtra. Ur videos are very useful and i am actually understanding this concept here only. I were gone through this topics earlier but here only I understood it in a better way. Thanks and God bless you.
according to Oracle Official documentation , Functional Interface : A functional interface is an interface that has just one abstract method (aside from the methods of Object), and thus represents a single function contract. Is it a functional interface? Yes. From the definition in the language spec: A functional interface is an interface that has just one abstract method (aside from the methods of Object) Will it be treated as a FunctionalInterface? Yes: However, the compiler will treat any interface meeting the definition of a functional interface as a functional interface regardless of whether or not a FunctionalInterface annotation is present on the interface declaration. I am droping link here: docs.oracle.com/javase/specs/jls/se12/html/jls-9.html#jls-9.8 stackoverflow.com/questions/56827701/is-comparable-interface-a-functionalinterface check it .
One suggestion - At the end of the video of any topic can put a slide of interview questions related to same topic so that in one place we can have all the information and can get to know after learning from videos how much answers we are able to provide.
@@amazingsketchesandpainting3319 you're sounding like nonsense. It is not a spoon feeding. To keep all relvant data at one place gives the clear picture of concept and ensure that we have covered all the relavant things.
I watched your multiple videos. specially Stream API was too good. I think your voice has magic .it's built trust among the viewver that something authonticate is being taught. So personally i belive so need to add your photo or video shot along with the syllabus you taught. THANK YOU!!!
It will be great if make another video for default and static methods allowance in functional interfaces. So, we have more than one method in functional interfaces.
Thanks Durgesh... Very nice and clear video to learn lambda. one thing i felt missing while explaining functional interface was : functional interface should have only one abstract method but it can have other non abstract methods(default) as well.
Sir aapka content accha hai but last me aap conclusion bhi diya kre with PPT slide...it improves your content Quality.....I hope you are doing well..... Thanks
whenever i need to know any complex topic of java then i just watch your videos on it and i never gets disappointment to know any topic you are simply the best on RU-vid👍😊
Sir if you used all 4 Functional Interfaces introduced in Java 8 while using lambda it would be very easy for us to grab it. Aarju Tripathi from your own City..
If any interface has more than one method then we have to use anonymous classs. Both have importance,we can't say after lambda expression, no use of anonymous class.
Areeee Sir Sir Sir !!! Thanks a lot Sir ji. You are my always go to person for learning anything new in Java that I want to start. You are the first and best fuel in my rocket that gives me a huge push/motion in my direction.
Thank You so much, sir. It is a very very nice video to understand lambda expression. once again thank you. Please continue this series, it will be very beneficial.
Hi Durgesh sir, Iam Deepak Kulkarni from Bidar Distric, which belongs to Karnataka, so i have learnt so many things from your video i all ways follow your videos. Thank you much sir 100% your efforts riches to us every concept is very clear thank you so much....
When you explain functional interface ensure to mention abstract method because functional Interface can have n number of method but only one abstract method
Best explanation of lamda ever . I have taken an udemy course to learn Java ,and i was stuck at lambdas .After watchng this video everything is clear !! Thanks . Will complete watching all your videos .
