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 - Low level Design for developing an admit card module for an app that generates admit card for various different universities.

Thanks for this video. I went through multiple video to understand the adapter design pattern but your explanation is much simple and up to the point and easier to understand with the example you provide.

I have watched the whole series all day today and I am almost at the end. I have very clear understanding of SOLID, Design Partners and how to explain them in an excellent way using this series. Sweet, crisp, to the point and totally worth your time! Thank you for your content lady!

@saumitrasaxena8470 Год назад

Hi , I am following your series on Design Pattern and must say this Adapter Design Pattern is explained in a very good, impressive and conceptual way . No doubts at all. Thanks a lot !!!! and must say great example !!!

Superb! Everytime I stuck at understanding something, I will come to social media. This time I stuck understanding adapter design pattern and divert myself to youtube. After watching this video I felt it I did a good job. Great example! I saw couple of articles and bought udemy course. Nothing worked for me. I felt worth to watch this video. I appreciate your effort on your creativity in using the example. The approach is neat, simple, elegant and higher ROI(time).

Thank you. For LLD interviews, I always learn SOLID principles and design patterns. But the application of those in solving design problems in interviews is getting difficult for me. Hope you cover 2-3 interview LLD questions and the steps and approaches to follow to solve them using all these SOLID and design patterns.

Thanks for the informative video, but the code part was not clear to understand, I got the anology but couldn't get the code example well.

@sankar1788n Год назад

Great example and explanation but now I have a doubt on what's the difference between an adaptor and a wrapper. Are they both same thing with just different names?

@payambassi8784 Год назад

The physical example is not bad the only problem is that they don't explain properly which class would be the old plug, or the not adapted one, and which class or part of the code is the new versio or the socket that would accept the new pins, like the students list that accepts the interfaced version of the Students college or school. So the explanation would be something like this: You have a two pin blowdryer but you are in UK and the sockets accept 3 pins. You need an adapter. An adapter has two characteristics, first the part where the 2 pins go in the second part where the 3 pins go in the UK sockets and in the middle the 2 pins are connected to the 3 pins coming out. In this scenario the schoolStudent is the two pin blowdryer and CollegeStudent is the Hair straightener that your uncle gave you when he came from UK so no problem there! haha, just ignore it. The SchoolStudentAdapter like a physical adapter, remember, has two significant role, 1st is to accepts the 2 pins and 2nd is to go into the UK 3 pin socket. So blowdryer -> adapter -> UK socket in code schoolStudent -> schoolStudentAdapter -> studentsList : schoolAdapter initialises with schoolStudent meaning two pin blowdryer goes into adapter, then second part of adapter which needs to have 3 pins for UK sockets is achieved by implementing or conforming to the interface give you the 3 pins which then goes into the studentsList that accepts only Student interface implementations. Anyhow it was a great video, I also really liked the explanation about the legacy code and new code.

Can only one type of object get adapted to a specific required type of object? Like in this example the methods used to return are .getFirstName , .getLastName, which are used only in student class

@sachinmukherjee29 Год назад

Nice explanation. I have one doubt how the Arrays.asList() method uses this pattern? This is the code snippet of that method public static List asList(T... a) { return new ArrayList(a); }

@shubhamMishraReal111 Год назад

Much better than the paid courses

@Hsn-Ab 9 месяцев назад

We can implement student interface directly in the schoolstudent class amd it will be accepted in the list So what's the point of writing extra wrapper class or adapter pattern in this case? Could you please help me getting this part ?
