Adapter Design Pattern in Java Theory

[@SajanKumar-zb2pr]

Thanks so much !! i'm asked same example in interview and i answered got selected....

1. You might be unable to change PilotPen(3rd party library case or an old class that is used by other teams etc.) 2. You want to use dependency injection. So when the available Pen type changes for some reason, you won't have to change AssignmentWork class. Also see open-closed principle. 3. AssignmentWork won't depend on PilotPen this way, so you can remove it from your project easily. 4. If PilotPen gets changed, you will only need to change PilotPenAdapter class.

Man, you are lifesaver

[@abishekraju4521]

Holy crap. This must be the best explanation on this topic I've ever seen. I had like a mini eureka moment at the climax of the video, esp. during the pilot pen part. SUBSCRiBED.

[@AshokYadav-np5tn]

i like this real world example of pen, assignment . thanks for this video .

[@harshgupta159]

So we’ll explained, please create videos for other design patterns too!!

[@vishaldindalkop294]

Thank you for the video

Am I the only one who hears "welcome back idiots" at the beginning? 00:00

[@eknathtake4920]

Thanks for this tutorial. This is the best tutorial I've got on youtube. It explains very important and tough design pattern in easy steps.

[@sukritakhauri648]

great explanation, just wao

[@meelmeel123]

thanks for saving me for my exam!

[@DagestanShop]

but cant we just initiliaze Pilot pen writeAssigment method ??

[@mixolt23]

So you could also say it maps methods with different signatures that provide the same logic onto each other?

[@atultripathi9166]

Nice explanation

[@Plays-wi1yx]

Was this video for adapters ?

[@mishrajitendra0111]

Can we make a standard or generic adapter pattern interface for multiple use case.

[@sairawadwa3774]

I don't get the proper concept like how I would able to use in realtime.sir could you please explain using another example

[@meena7222]

Great example

[@harshverm776]

Sir, can you share the Repo of all this.... Design Pattern Lectures...

[@TysonGill]

nicely explained

[@wBacz]

I don't understand why just simply not use PilotPen in class Assignment Work instead of using Pen interface in class Assingment Work? Or why just not make and interface with default method write and let class PilotPen implement it and AssigmentWork implement it too.

[@mallinani108]

Let's say PilotPen is implemented in 3rd party library and you don't have access to implement the Pen interface. And one more thing in future some other library or project will provide another type of implementation which is also hasn't implemented pen then adapter pattern will be useful to supply your implementation without worry about implementer. Real time example will be slf4j library if you supply Log4j implementation it uses that, or else you can simply change the logging to logback without changing the code.

Thank you so much!

[@RaushanKumar-co3wj]

i am searching for all design pattern tutorial from you. If you can you give me the link?

[@nincako]

why don't you make PilotPen implements Pen instead?

[@gijish4u]

To not change the implementation of PilotPen I suppose. Adapter helps to use both Pen and PilotPen as it is.

[@soho1080]

Something seems to be missing here. Where is the original concrete implementation of Pen that the PilotPen needs to adapt to??!!

[@AkashGupta-mz5ed]

What is director here??

[@hasnahoque2817]

So helpful

[@gauravupasani9088]

The explanation is good however what I don't understand is why do we need a Pen Adapator itself. In the hardware world it makes sense that you repurpose the same charger. Thus you don't have to buy a new one. But why in the software world why not just directly use the pen instead of relying on this adapter thing ?

[@pavankumar-si2jv]

Awesome

[@mrchedda]

am I crazy or is this just sub-class with an override method? Why not just explain it that way?

[@gunasekart.j3552]

Anyone in 2024
