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...

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

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 ❤ .

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 ?

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.

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 ?

@madhurpachauri297 Ай бұрын

Hi Shrayansh, I have a doubt in the prototype pattern, in the start you have said that we should not create a new object as it is a heavy operation, so we'll clone it using prototype pattern however we still end up creating a new object of the Student class. So how it is solving the purpose ?

@ConceptandCoding Ай бұрын

In the Prototype pattern, the new object is created by copying (cloning) an existing instance rather than instantiating a new one from scratch. This can be more efficient because cloning can be faster than creating and initializing a new object, especially if the original object has already undergone complex setup or initialization.

In prototype design pattern, can't we just write like - Student cloneObj = obj and it will copy all the properties of obj into cloneObj , right or is it not a good practice? Thank you sir for valuable content ❤❤

@ConceptandCoding Жыл бұрын

It will be shallow copy. Means if original object change, prototype object will also change. Generally good way is deep copy.

@ketanlalcheta4558 Жыл бұрын

Thanks a lot for amazing content as always I have a question on prototype use case. Agree that we dont have access to all data members in client code(main function). But what our protoype is doing ? It just adds clone method inside the class and creates new object taking existing object's data as it is. Why not then copy constructor ? Both does not solve the same purpose ?

@ConceptandCoding Жыл бұрын

Very good question Ketan. Understand with this 2 usecase: 1. In your client code, you exactly know the object for which you have to do the clone. Ex: student which we have done. You can also do deep copy constructor. 2. But what if in case of Inheritance, (you have many children classes). And in Client method you have interface Object and you don't know exactly which child constructor you have to call. In that case Prototype pattern helps. So i would say, copy constructor is not scalable, and Prototype Pattern is scalable. Let me know if it clarifies your doubt.
