What is the Prototype Design Pattern?

Type of videos i've been waiting from mr. Neetcode gaddemnit

Goat back at it again

Love your design pattern videos

But all the members within the class should also be clonable for a deep copy to happen. The example you provided seems to be one of the trivial scenarios. As per my understanding, we should not be able to do a deep copy only if all the members implement the clonable interface / are primitive data types.

if the cost variable is private then how come we can fill it in the first go ?

Do you just hand write with the mouse? I hear the mouse clicking in the video background

Sir please post video solutions of weekly contests🙏

Nice video man

are you sure that new ArrayList(images) performs a deep copy? I just recently implemented this at my work & it didn't work. the ARRAYLIST was a new reference in memory, but each object in the list pointed to the exact same object as before. (Shallow copy vs deep copy). This is VERY important if you intend to modify the underlying objects! also: pin me please

[@NeetCodeIO]

It depends on the what the list stores. You're right that if it were a list objects, it would not perform a deep copy. If we were storing primitives like ints, it would create a deep copy. Strings are unique since they are immutable. Technically it's not a deep copy, but since the strings cannot be modified it doesn't matter in this case. But you're definitely correct to point it out.

Programming in Java again are we?

Can we have a video on api naming for non CRUD operations or atleast what standard they used to follow at Google. Most videos or tutorials on the internet just cover the basic CRUD stuff. Would be really gratefuly if you can explain how to name apis for more complex use cases like file upload, file download, login, logout, reset password, send otp etc ie conventions for non crud operations.

[@harrydayexe]

Almost every example you gave is a CRUD operation

[@adesh116]

​@@harrydayexe let's say login.. i felt it's a non crud operation because all u create is a token.. u are not updating nor creating nor deleting a resource from the database.. let me know if my reasoning is wrong here

[@ecchioni]

Isn't it just a copy constructor?

[@NeetCodeIO]

In some ways, but since they have the same subtype it adds extensibility. In the code walkthrough we clone a list of objs which illustrates this.
