Great content. Just one addition to the built in functions - if you have a requirement where a function should have no arguments and returns nothing (void), you can use Runnable. I think that is another use case of Runnable, apart from threads.
Thank you for this explaining very clearly. The concepts and topics you explain in your video is extremely flawless and with simple examples. Have been following and liking your videos from quite sometime now. Please keep up the great work you are doing.
The notes are a great way of revising. But in few class notes where you have pasted screenshots, they are very difficult to read. Please try to look into this issue
hy shryansh, how much time it will take more days to complete java full concepts ? can u tell me date when all completed so that we can move on springboot & microservices
Hi Gnana, currently in a month i am able to upload 6 videos. If i go with the same rate, i think next 2 months we will be in good position with Java. But i can not commit bcoz generally i prepare the content on weekends.
hi sir, thanks for this lovely playlist Right now I'm struggling with practice coding questions as I'm not able to find satisfactory number of question on the internet, especially for GENERICS, FUNCTIONAL INTERFACE AND STREAMS. can you please let me know where and how can i search for them, please.
Hi Shrayansh, just a doubt at 26:11 , you said that Living Thing is a Non Functional Interface but since it has just one abstract method, it as well is qualified to be a functional interface.Just that there is no @FunctionalInterface annotation on it.Or is it non functional interface because of the presence of public access modifier(which should not be the case as all interface methods are by default public hence making functions Interface's abstract methods public as well.)
I need to check the video, but as per your description, access modifiers is not the reason. Annotation is not there means it's not a functional interface but till it has only one abstract method, we can use it as a functional interface but there is no control any someone can add another abstract method too.
yes you are right. LivingThing is also a funtional interface. but still Bird Interface can't extends it. bcs Bird Interface is funtional Interface (restricted by @FuntionalInterface) so it can't have more than one abstruct method. I think Shreyansh has just taken example to give understanding to us. but he can add one more abstruct method in LivingThing interface so it won't confuse others
@@ConceptandCoding "Annotation is not there means it's not a functional interface...." It fulfills the criteria to be a functional interface. It has SAM. And you yourself said the @Annotation is not mandatory right?
Hi Shrayansh! I recently enrolled in the Java + Spring Boot course on Udemy, and I’m really enjoying the learning experience so far! I’ve noticed that for some videos, the resources section isn’t yet updated on Udemy. If possible, could you help ensure that all resources and materials are available as the course progresses? Thank you so much for your support!
@@ConceptandCoding I've explored only the Collections section so far, and I noticed that the documents aren’t fully updated with code snippets for Set and Map. While I’ve grasped the concepts well on the first pass, having these resources updated would make it easier to quickly recall and review the material when needed. However, it’s not a big issue-just a suggestion for added convenience.
Just wondering why Java creators introduced Functional interface at all? Just to make normal interface class with single abstract method more restrict ?
If a functional interface (which do not provide any method inside it) extending non-functional interface which has only one abstract method, then this will work right?
yes, currently our rate of video going is 2 videos per week, if i am able to maintain the same consistency, by next 2 months i will be able to complete the JAVA
Amazing video sirji..but before starting system design ....what are the prerequisites? i am covering this java playlist now .....can i start your LLD series after that?
I understand functional interface, but in real life interfaces will have more than one methods, so using interface with only one method in it rare case know?

I will re-visit this lecture again.
have you revisited ?? if no revisit again please
Very neat and detailed explanation
topics are very nicely covered/presented. 🎉🎉🎉🎉🎉🎉🎉
It is beautiful explaination because it is very simple.
One more interesting topic which is method reference could have been explored here in this video.
clear everything ...great😇😇😍
Very well explained. I have understood and concept us well understood
nice explanation...

Right now I'm struggling with practice coding questions as I'm not able to find satisfactory number of question on the internet, especially for GENERICS, FUNCTIONAL INTERFACE AND STREAMS.
can you please let me know where and how can i search for them, please.
is it necessary to have generic class in the supplier , consumer type?

Can you share PDF downloadable link instead of ZOHO link of notes?
Please add notes slide, it is not in the description. It will be very helpful.
thanks!
from video no. 15 onwards notes quality is not good. we need to zoom notes to read it. when doing zoom content got blurred.
create ur own note

Hi shrayansh, for using lambda expressions, do we need to declare interface as Functional Interface?
Declaring the interface as functional interface is not mandatory, until you have only 1 abstract method.
Hi Shreyansh, Please make video on java 11 features.
Will do, it in my bucket list
Hi Shrayansh, Till when all Java topics will be completing? next 2 months ?
yes, currently our rate of video going is 2 videos per week, if i am able to maintain the same consistency, by next 2 months i will be able to complete the JAVA
@@ConceptandCoding Thank you shrayansh🙏
Hi Shrayansh, will you be covering stream API also ?
Yes, in collections
sir if we become premium member can we access all videos in the channel?
Yes buddy
Amazing video sirji..but before starting system design ....what are the prerequisites? i am covering this java playlist now .....can i start your LLD series after that?
Yes, we are good with starting LLD after you know any OOPs language
Video is uploaded on 17th nov 2023(11 hours ago ). how come your comments are 4 months ago ?? Just wondering
Is it compulsory to use wrapper type variable in parameter, if we make generic type of interface?
Yes.
Hello Sir one question might what should we use with spring boot Gradle or maven in a personal project if I plan to use microservices in that project
Try to use maven. It's very popular among MNCs
I understand functional interface, but in real life interfaces will have more than one methods, so using interface with only one method in it rare case know?
Yes generally it's very rare you write your own functional interface, generally we use existing functional interface only
Notes link??
