How does Builder Design Pattern solves problems like URL creation?

Learning system design is not a one time task. It requires regular effort and consistent curiosity to build large scale systems. Moreover, every system has different requirements and meeting them requires expertise and people with varied and specific knowledge. There are a lot of resources to learn through videos. But not everyone enjoys that mode of learning. Instead some people understand things better by reading and thinking on the points put forward by the author. Such people can access these in different ways - blogs, articles and books. We have come up with this video to put light on one such aspect, that is - Types of Design Patterns

I saw a couple of videos for builder patterns but this is really crisp and useful. Great, keep 'em coming.

[HariShankar-yfdi]

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

[PiyushPragyan]

Loved the design pattern series. I understood this in a single go. 😊

[shubhamrajput]

This is the best explanation I have ever went across for Builder Pattern. Thanks a lot for your work, really grateful to you !!

[letsdosomething]

Mam your way of teaching is just so amazing..it gives an extra view to see the code and to understand the code in easiest way.grateful that i found you

[sekharsamanta]

Best ever video I've seen so far on design pattern

[AshutoshSingh-mhqm]

what a nice value addition to my engineering life. I am enjoying watching the design pattern playlist. It's above par comparing to any paid courses. Thanks a lot ....

Finally in forever i understood this concept!!

[jokhakararpan]

Hey Yogita,
You have explained this in very simple way, with practical example.
Really liked your work.

The way u organize the course is nice. This is a simple design pattern which lacks the concept of OC principle.

[narenshalivahana]

superb example and explanation, understood in few minutes

[aviator]

Best series on design patterns please complete rest as well

[aakansha]

One of the best explanation on builder design pattern!!

[letsrock]

In office I was writing code this way all along...just by following/understanding already written code... Never knew I was utlising Builder pattern

[hbhatia]

Refactoring has become very easy in this pattern with some cons to use according to usecase.
Thanks for video.

[AditiAgarwal]

Such a crisp and easy-to-follow video. Thanks for making this... :)

[sumantkumar]

Very simple and easy to understand, thank you for the design patterns series.😊

[prabhagaikwad]

Loving whatever content you are creating. Most easiest ways you try. Much appreciated. Thank you so much _/\_ _/\_

[blitzc]

Beautifully explained! Subbed, Thank you!

What if we try to make it un-immutable.
I removed final from fields and then created getter and setters as well to make it un-immutable. I don't see any issue. If any?
