Thank you so much Shreyansh, I can't tell you how valuable your videos are. When I am watching your videos, the time simply flies. Keeping audience engaged is an amazing skill in an educational YouTuber. Keep making great content ❤

[SakshiGupta-vzoj]

I feel very fortunate. Whenever I am studying LLD, I can stick to this playlist. Thumbs up to the content, such teachings!!

Your content is always far better than other YouTubers, keep making more videos .

Hey, I'm having one doubt -> You told that to avoid the expense for creating the instance, we will use clonning... But in the clonning also, we are using new classname(); to create the object... It is just, it's happening on the different place but what's the difference in this memory wise... It is still creating the object...

[jayantjain]

Builder Pattern actually solves the main problem of having multiple constructors for a single entity class. Let's assume a class has 8 data members and you may want to use some data fields at time and not at other times. So for 8 data fields 2^8 constructors are needed to cover all cases. With Builder pattern you dont need these 2^N constructors just use the power of setters and in a final builder() you get the object you want. This is the only purpose of builder pattern, rest other patterns are very well explained . Really loved it ❤ .

Thanks for consolidating all the creational design patterns in 1 video! Great way for us to revise all the patterns. Expecting the same for Behavioral and Structural patterns

[oluchukwuobi-njoku]

This was perfectly wonderful, thanks a whole bunch for posting

[harishable]

What exactly i was looking for !! Thanks sir.

[varshareddy]

This is perfect !! Thank you so much 😊

HI sir I have a doubt.
In prototype, we have a complex object expensive to create, thats why we don;t create it but clone it.
But in Student class, within the overridden method we created new object with new();
so we are creating the new object with same data, everytime its requested.
so its again an expensive process to do and it defeats the purpose of having prototype.
I am really confused

[YanishBansal-js]

Is the example used in prototype pattern is wrong ?, I mean what is the use of cloning a derived class when its base class have only one function and i.e clone, when returning a derived clone you will only have data of base class because clone function in base class has base class type ?

[snehaldeshmukh]

Vey nice Session Shreyansh!!! Keep it up :)

[SatyamKumar-bwvi]

Hare Krishna..! Bhaiya Great Video & effort also..! Please continue.

[sumitbasu]

Thank you so much Srayansh..very helpful for us.

Shrayansh: Thank you for your good work.
One doubt regarding Prototype, you are mentioning to create separate interface with clone(), and all the subclasses will have to override that. How is this different from Cloneable interface, where we don`t have to create the interface separately, and clone() consistency remains the same in all sub-classes.

[khawajasaif]

Great, please create for others design patterns also with one video for structural patterns and one video for behaviour... Thanks in advance

[sandyatangudu]

Thank You so much for the videos.Anyone can understand these videos.Could you please difference between volatile and atomic variables.What happens if we use volatile keyword instead of synchronized method in singleton pattern

[rraviu]

Builder Pattern :

How can you assign dynamic values in Director while creating objects ?
It seems in the video, you have used static values.


And for order maintenance, is it really the responsibility of Director ?

Singleton using enum where serialization is not required
