13. Proxy Design Pattern Explanation | LLD System Design | System Design Interview Question | Java

Sir Please code ko aur acche se samjha diya kariye

Do you think it makes sense to use singleton pattern for EmployeeDaoImpl? Also making the proxy object singleton (in the case of multiple proxies, implementing singleton for all the proxies) ?

Thankyou for the video I ahve been following your LLD playlist and its been useful. Although Can you also tell how the response is sent to proxies before giving it back to client? Does the EmployeeDao class also need to have has-a relationship with EmployeeDaoProxy in that case ?

can some one send repository link pleas

in your employee example what are the other benefits of proxy class..this authetication task can be checked in concrete class as well..? college me proxy server wala example i understood bhai.

I am thinking of middleware while watching this video are they similar?

nicee

Could you add subtitles in english ?

Hi Shreyansh,
looks like you missed adding the code for ProxyDesign Pattern in your repo.
Can you please check it?
OR
if someone is able to find it, please give me link.

is this same as middleware in nodejs?

ye kuch decorator dp jaisa lag rha

There are some design patterns code are unavailable. Please provide it.

It felt like decorator pattern which has and is relation exist... whats diff?

Hey, thankyou for such a good content. Could you please add code for all design patterns you taught in this playlist on your gitlab link? It would be great help.

In the constructor of proxy class we are creating a new object of implementation class.Shouldn't that object be passed as constructor injection?🤔

Why don't we place the validation and other part in employee table class? Is it because of Single Responsibility Principle?

thanks a lot for this amazing tutorial!!

Hey , here what is different b/w proxy and facade, ? Here i can see instead of proxy we can achieve same thing with facde pattern also , right?

What is the difference between this & Chain of Responsibility pattern ? In COR pattern, we keep seperate handlers and handles the validations or other business logic separately.

Can we use this pattern to avoid null checks for Strings?

Hi, How will you restrict the client from creating the object of EmployeeDoaImpl directly? We want EmployeeDoaImpl only created through EmployeeDoaProxy.

Great video , thanks

Bhai playlist ulti hogai hai, sahi se isko kaunsa video pehle dekhna hai us hisab se arange kardo. Ya bata do kis video ke baad kisko follow karu?

Good examples given in this video.

Bhai, aapka channel grow ho raha hai

Hi, Can you please cover all possible important design patterns please? the way you explain will help a lot in understanding.

Hi Sir, I have a question regarding learning these design patterns how you have learned these concepts by yourself like have you seen videos or through documentation.

In a broader sense, I want to understand how to learn a new concept on my own, for lld I have you videos but in long run I have solve the problem on my own how to build that mindset. Please Suggest.

Which design pattern is best suited for designing an authentication service? Is proxy pattern the one ?

Hi .. please cover all the design imp patterns as soon as possible... Your videos are extremely great... the way you explain is quite awesome 🙂
