Hi sir I have a doubt in flyweight pattern like in robot eg we are creating only two object one for human type and other for robotic type as they are cached , their extrinsic value is their coordinates now suppose we have created human type robot and set is coordinate (0,0) and now again we have created another human type robot this time we will get same object which we created before from cache and set it's new coordinate (1,1) Wouldn't it create a problem becoz coordinate of first object is changed from 0,0 to 1,1 and now the robot from 0,0 will display at 1,1 Can u please help me to solve this🙏

Hi sir I have asked this question previously plz reply sir In command pattern we have an invoker, but the client can directly use command and pass the receiver to command there is still lose coupling between client and command. Invoker can only be used for undo operation if we don't want to have undo operation then I think there is no need of invoker. And the uml that I have seen client doesn't have HAS-A relationship with invoker
No, if client can directly give Command, then it has tight couple with command class. If suppose any command giving process change, client has to make the changes too. That's the last thing which we wanted (i e to make client changes). That's why invoker is added, it's just an abstraction layer for client, so that in future any thing changes it will lead to change in 1 place i.e invoker, bcoz you can have multiple clients but invoker class would be 1. Hope that clarifies
@@ConceptandCoding sir can u plz give me any example of how command giving process change effects client, in chat gpt i have searched it says we can use command pattern without invoker for simple design
@@yuvhrajverma9665 Yuvhraj, then without invoker it won't be considered as Command pattern, and definitely you can solve the problem without invoker or even without using any design pattern, usage of design pattern is not mandatory. Consider very simple example: let's say i changed the command method name from "switchOnAC" to "turnOnAC" , will this impact client? Yes , client has to change the name too, what if you have 1000s of clients, will you change all? If you have mediator like invoker, you have to change only at invoker and clients remain un impacted

Hello brother, Are you also going to start spring & spring boot series, as it will help a lot and one can learn everything starting from java to spring boot. Thank you for these videos.
@@ConceptandCoding hey , i like the way you teach. Thanks for making this playlist. I cannot see the link in description for this video and few other videos as well. Could you please check.
try{ method1();} finally{} lets say method1() throws runtime exception and there's no catch block to catch exception. will finally block get executed. I think program will stop abruptly and finally block will not get executed.
@@ConceptandCoding for unchecked, no catch block is needed and finally executes before program ends abruptly. for checked, throws is mandatory both in exception thrown method and from called method, if there's no catch.
bhai your videos are explained in detail but you are not using any editor for the example of the topic..this does not boost the confidence of the viewer...please make videos in which you do coding also with the concept.
Thank you for teaching Exception Handling in one go!
I really like the way you have used the code snippets without actually coding on any IDE!
Your Explanation is Very Clear as well as in Depth. [Please keep on teaching in Depth.] Thank You Shrayansh Jain.
Thank you
Please post notes for all video in a post, so that it will be helpful for us to revise for our interview. Thanks for the video bro. No doubt, great video for people aspiring to be Java Developer
we cannot classify into checked and unchecked because its an error but we can say its unchecked bcz it only detected at the runtime ...
Akshay Saini in javascript and shrayansh Jain in java both are amazing 🚀🚀
Thanks a lot buddy
Yes bro I too got the same vibe❤
Hi Shreyansh, can you suggest some problem lists or assignments which we can practice on our own?
Gfg website has around 34 Question set on various core java topics.

Thanks shreyansh for great explanation
It's worth to buy subscription next month i have placement . & this video help me lot🎉
good luck for your placement and happy in depth learning
After we stop membership then for how long can we acces Zoho notes link??
Does anybody knows?
What is type of user defined exception if extended from Exception class , checked or unchecked?
ack of the question
@@ConceptandCoding ?
@@sagarsingh-wb8ou In Java, if a user-defined exception class extends the Exception class, it is considered a checked exception.
at compile time its checked
Hey Shrayansh, do the throws keyword after the method all the way upto main() also not break the flow of program??
Not sure but I think error will be un-checked type exception.
Aap कहाँ थे प्रभु
Where is community section ??
@Concept && Coding
Can you add video in stream API in java also i think that is missing in your playlist
It's next video buddy
sir where u put the notes.....?
pls share the link
Pls check the description section buddy
Great Explanation !
No bro not practicing ,how to practice pls tell that also😢

In case of big applications which are deployed in servers, if runtime exception occurs..which is not handled, will the entire application stops?
No not entirely application, that particular request will fail only.
@@ConceptandCoding But if incase for some logic in application out of memory error occured , then the application server will shut down right ??

Error is unchecked exception, as it's throws error during runtime only.
Right
Error must be a type of unchecked , runtime exception
try{ method1();} finally{} lets say method1() throws runtime exception and there's no catch block to catch exception. will finally block get executed. I think program will stop abruptly and finally block will not get executed.
Finally block will get executed.
But do try it out.
