How flyweight pattern helps in memory optimisation | Design Patterns | sudoCODE

[@nagendrapalla4433]

I went through all the design pattern videos that you created so far. The way you explained each design pattern with an analogy is excellent. I hope you'll create more videos on the remaining design patterns. Thanks for your help to understand these design patterns in a very easy manner.

[@dhruvsolanki4473]

Just completed this LLD playlist and understood everything easily as your explanation is very good. Thank you for sharing with us.

[@apiyush]

Concise, crisp and easy to understand LLD playlist. Thanks, Yogita!

[@akashburnwal1999]

Hi Yogita, thank you for covering low-level design topics. Your explanations are really helpful. Could you also cover the Strategy, Observer, Decorator, and Prototype design patterns as well?

[@RohitPatil_Tech]

Hi Yogita, I just now completed your "Low Level Design Primer Course" youtube playlist. And I have to say that your explanation and analogies in the videos was simply fabulous. Appreciate the good work your are putting out. Thank you!! 🙂

[@KKKK-pl8yf]

Binge Watched your LLD playlist. Very highly structured content. Loved your way of teaching. Thanks Yogita !!

[@ashisranjandey635]

Awesome awesome awesome. these kind of backstoy and explanation is what gets me motivated. thanks for sharing.

[@tesshsu1]

Came to this video and so far most easy to understand, tks

[@Abhishek-Khelge]

why did you stopped in this series ?

[@Abhishek-Khelge]

best explanation of all the videos

[@rahulvaish3034]

Loved it! Thanks for posting this amazing video.

[@simiiv5021]

Thank you for the LLD series!

[@kudaykanthreddy]

Thank you for the LLD playlist and for the amazing series. However, the descriptions of most of the videos are stale or wrong. Can you please look into that as that is causing confusion.

[@SankalpCollege-f2o]

Playlist completed 🎉

Hello Yogita, with this pattern we are overriding objects which has individual properties right as it is returning same reference per color and url. At end we will have only 3 objects(we may have many reference but all points 3 objects) based on the colors we have defined in that examples. Here I am not able correlate with this examples as we are seeing many balls. Plz correct me if am wrong.

[@sumanrana4083]

I also agree with the above statement. I think there should be one BallType class that should contain only color & URL. And there should be one field ballType(BallType) in Ball class. @sudoCODE

[@PremKashyap]

@@sumanrana4083 You are absolutely right. It looked buggy. So I wrote the code to verify it.

[@ambarishhazarnis9531]

The intrinsic properties are resused from the cache. The Ball object just has pointers to it. Java does the same with its String pool.

[@PkSam07]

​@@ambarishhazarnis9531No. In the for loop we r fetching one of these 3 flyweight objects randomly and then we r updating extrinsic attributes one by one in one of these 3. Now, in the game screen - How come at a time, these 3 objects could have multiple extrinsic values? In that case these 3 object should blink at different coordinate position(in such a type logic). I think this loop should be about creating 10 object and after transition (like as per Yogita) there should be 11 = 10 + 1 flyweight where each one will be using flyweight object. Now, How each will use this flyweight object that's confusing?

[@PkSam07]

​@@sumanrana4083Correct! This BallType could be name as FlyweightBall having intrinsic data. And this factory could be FlyweightBallFactory which will return this flyweight object and then in forloop we could create Ball for each loop; setting this flyweightBall having one more field like u mentioned. Or else can move this extrinsic data setting as well inside BallFactory and can create complete Ball object inside Factory itself. Thanks!

[@UpendraSingh-qx5uh]

I have one doubt lets assume i have one red ball having radius 10 and now i want to create one another red ball of radius 5 then as we already have red ball so no new Ball will be created on previous ball extrinsic properties will be overridden then how we will have two red ball?

[@gokulsrinivasan8563]

Kindly cover Adapter, Facade and other patterns . Thanks for all the fruitful content!!😀

[@surajsharma-65643]

The way you explain, its super cool

[@PaulPronabananda]

Thanks for the great explanation. Code is not available in the description section, please share the code also.

[@whereisinfinity]

I just finished this LLD series and I can say with utmost confidence that it's absolutely the best among all the available sources online for LLD. Why have you stopped this series? I really hope you continue this awesome series soon. I am sure a lot of us would be willing to pay for your content as well.

[@sudocode]

Yes I am coming back soon ☺️

[@whereisinfinity]

@@sudocode Great to hear!

[@abhishekjaiswal3673]

Hi Yogita, Thanks for making such videos. You have explained very well which good examples. Waiting for strategy desing pattern with good example of why we should choose composition over inheritance.

[@BhooshanMusic]

great example. Do we get to know who the autonomous vehicle engineer is ?

[@asjjain191183]

Thanks for explaining such a complex design pattern in easy way4

[@sudocode]

Most welcome 😊

[@aneksingh4496]

Your videos contents are very good ... but make it bit slow to digest ... also include live (fast manner )coding would be better

[@AdityaKumar-iy8vl]

Thanks alot for these videos

[@swatiacharya9073]

Superb animation

[@tirunagariuttam]

how about we make the intrinsic objects as static. That way they remain at class level.

[@colinmaharaj]

Interesting, I'm trying to create an automated trading strategy from my knowledge of programming on my little knowledge of trading.

[@pyjamchap]

Yogita, 👍 nice job. Keep going. Need command & strategy pattern.

[@sudocode]

Sure 👍

[@rishabhjain4024]

Did anyone know where can we find the code showed in videos

[@AhmedIbrahimGhnnam]

please, how can i find out the codes for facade design pattern and flyweight design pattern??

[@snadeem9448]

On point explanation 👍🏻

[@sudocode]

Glad you liked it

[@HariShankar-yf8di]

please make videos on remaining design patterns

[@suraj.mohapatra]

What is the name of that stock trader who became a software engineer and now working on computer vision and working on algorithms for self driving car.

[@sudocode]

That would be my husband 💜

[@deepakp2936]

Yogita, The contents of the video are very good. But I missed seeing you explaining the things. I hope you are doing good.

[@sudocode]

You would see me very soon.

[@chinnunarra2744]

Good explanation

[@sudocode]

Thanks for liking

[@ascii8681]

Can't Inheritance solve the same issue ?

[@sudocode]

No, it would still create new objects which will occupy a lot of memory.

[@designpathy]

The example you have shared is wrong. Properties that do not change should be part of another class, example : BookType. Using composition add BookType in Ball class. Please everyone do not assume everything online is correct, do your analysis as well.

[@ishimweanna7904]

I can't see source code

[@rishiraj2548]

Thanks a lot

Happy to help
