Superb lecture. I saw 2-3 other youtube channels for understanding builder patterns. Many tried but were not clear due to bad examples, difficult code walkthrough. What separated this video from Yogita is that she explained the painful areas of non-builder pattern based examples, she explained a technical jargon of constructor telescoping, the examples made great sense, two example codes to make the understanding crystal clear. @Yogita Thank you so much

Hey Yogita. Huge fan of your video, crisp and easy to understand. For this (builder pattern) implementation, saw some other sites as well, seems like 1. using inner nested class is not the only to implement it. People are using combination of (interface and abstract classes to achieve the same). 2. In your implementation isn't the code duplicated, as in the UrlBuilder and Builder class, you are writing the same fields again. Looks a bit messy. Dont you think?
@tenshin1116 ай бұрын
This is a good introduction into the Builder pattern but it misses a few things. How about making sure that required fields are actually enforced in the code? Right now nothing is stopping you from building the URL that contains only 'path' and 'query' parameters but is missing the protocol/hostname part.

Doesn't the objects still have other optional fields with value null? Its just like using a constructor with all params . Does it just helps to remove the extra nulls ,that we need to pass to the constructor, with all the params?

Thanks! I just have one question. Why use inner static class here? Why can't we have those constructors directly in URLBuilder instead and chain individual constructors that return type URLBuilder?
@PkSam07 Жыл бұрын
Yes, I too tried so and it worked. Just fields and then field method which return object itself. Moreover, I removed final from fields and then created getter and setters as well to make it un-immutable. I don't see any issue? You found any ans?

One correction: builder.build() call should actually return the URL object instead of the builder object. This builder object is part of the URL object constructor such that the value set in the builder could be used to construct the URL object. Am I missing something ?

But at last after using builder design , the URL class is of no use? what i mean to say is , we should be able to print url.protocol , instead of urlBuilder.protocol.

Firstly we want do not want to use the new keyword(which Factory pattern solves) and second we use builder pattern to make objects immutable.
@ashish2610962 жыл бұрын
First of all thanks a lot for this series, learning a lot from it. I have one doubt, in build method we are hardcoding URLBuilder class. Can we somehow use factory pattern along with builder pattern to create the URLBuilder object? so that in future, if I need to create TinyURLBuilder or any other object I can do it with minimal changes

7:41 People probably wonder why create a new object based on an existing static object instead of only using one? In other words: Why going through the hassle of a static Builder, private constructor and _new_ in URLBuilder.build() instead of just populating the _new_ in Demo.main()? The answer is immutability. And although it's not needed in this particular example, it's a clever example to follow in other situations.

Imagine you have 10+ params and you just need to create objects with 2-3 values set. You will have to write null in all unwanted params place. (extra work) Imagine you need to create multiple similar objects. (unwanted code, extra work) Builder pattern to the rescue

You did not explain why we can't use setters only? Yes, the code looks redundant but I would have liked some explanation over it. Moreover, @Builder annotations for classes allows its objects to be modified.

If there's no need of immutable object, then there are alternatives to builder. But immutability is a good thing specially in a threaded env.
