🔥Singleton Design Pattern in Detail | Multi-Threaded Environments | Hindi

[@naveedzaman3533]

Hi Durgesh, After a considerable amount of time, I've finally found some valuable resources to study design patterns. Thank you very much. I'm from Lahore, Pakistan. Regards, Naveed Zaman

[@SARTHAK-IO]

Bhai bhai 😂🔥🔥🔥🔥, literally itne depth mei aaj tk kisi ne nh padhaya ,

[@ankukulhade786]

i have seen many video of singleton but never seen such video. Thanks for sharing.

[@adityabhadoriya3191]

It's good that you are maintaining a playlist general questions are asked in project interview that your project is based on which design pattern or what approach we need to use to accomplish this task which design pattern. etc..,

[@susmithanadar4034]

You make coding feel so easy.

[@hrds479]

glowing fire while typing nice it look amazing

[@Kahanikduniya-q6i]

Thank you sir , itna ache se to paid course me bhi nahi sikha hoga kisi ne ....:)

[@Ritesh00777]

Thanks durgesh Finally I found a good and simple explanation on design patterns it's easy to understand and adaptable

[@souravdas6918]

bhai thank u.. jalebi samosa example se single ton pattern ka doubt clear ho gaya ....

Bhai aapne Eager way me private constructor kyu nhi bnaya?......Without uske hum kitne bhi object pna skte hain pizza ke. Please clearify these small mistakes can ruin our interviews. btw Awesome work , Thank you.

ur just great man

[@pawanpathak6576]

Hi Durgesh, Thank you very much for your contribution for making us understand such complex technicality in such a layman way. Please keep doing the good work. However I will like to bring this in your notice that in Eager Initialization of Singleton as We have not created private constructor of class, We can create the object of the class anywhere else. And this might lead us to develop faulty singleton. I was going through coding practice of your code and I tried to create object of Jalebi class in Example class which allowed me to create 2 objects with new keyword and when I checked the hash code of these newly created objects, It was different. I might be wrong, Please help me.

[@MayureshDiaries]

Just a quick question. In Jalebi class we also have to make constructor private right?

[@varaprasadpamarthi2649]

super explanation video is length but worth watching , thanks for your effort😊

[@dailyyogaathome]

Well explained Durgesh! Please create these videos for Python if possible!

[@Abhishek-df5tf]

Why arr used dark theme

[@unemployedcse3514]

Awesome 😍

[@dProfessor_]

got it sir thanks

[@devkumar9889]

We can also use Static data and members instead of singleton ?

[@callmeghostgamer]

[@strangemate]

Hi Durgesh, what is the reason of providing the class literal inside the synchronize block?

[@rupeshpatil6005]

ThankYou Sirji Sir Please make This Design PATTERN PlayList we Want More Videos

[@sukrit_shukla]

Hi @Durgesh, Using synchronized block will not work in distributed environment. We'll have to use enum for handling singleton creation in distributed environment.

[@sameerkadgaye2048]

Thank you sir

[@djj.-gq4dl]

Man only 1 Samosa for all? that's evil haha! i need atleast 5 instances of samosa lol. Love ur video. I am from California! Can you also share what does @Singleton does?

[@Javawala-i6z]

Great sir

[@v2factsand327]

Awesome

[@LowProfie_]

Sir, please keep the background in light color. 😢 Some students may have problem with reading dark theme. It's not properly visible. We have to keep brightness at Max. 😢

[@sarahsheikh17]

Wah! Ek video me 6 mahine ki semester ki parhai ho geya.

[@vinaychauhan7627]

Hi, I do have a question, Why are we using extra if condition and not making single if condition as synchronized block?

[@ommehta4501]

very good please make the live project using these design patterns

[@RiteshSingh-q4b]

Hi Durgesh, why you did not pass private constructor in eager way of creating singleton?

[@ketank6864]

awsome!

[@AnuragKumar-kf4ic]

Can you give example where to use lazy and where to use eager?

[@shubhamsinghal7188]

Sir, Poha bhi banado toh pura nashta hojaye 😍😍

[@shpreetamsingh1263]

Hi first time connects successful with db by class object but after some time when I am calling again class object then db connection get time out. Any suggestions ?

[@aparajitas4303]

Hello from Virginia.

[@rohitjaiswal946]

Why we used if(Samosa==null) before and after the synchronized block, what is the issue if we use it only after the synchronized only?

[@deepakkarmaDK]

Could please create series using c# ? Synchronised keyword not in c# .. so how it will work in c#

[@amitsaonerkar6640]

Is it not like the static variable samosa in class when accessed by different threads can get its false state. For e.g t1 enters get it null and create it and then t2 enter but its updated state ie samosa is not null is not reflected for t2 then it can also lead to its creation . Basically keeping it volatile may solve the problem.

[@palkherohit1]

have one question, what if we don't define constructor. Is it mandatory?

[@avrajitsikder9646]

if you don't define define constructor , JVM will invoke the default constructor. But when you define a constructor as your way it restrict the invoke of default constructor. For that it is mandatory.

[@JohnSmith-vm6ln]

Bhai isko dekh ke bhuk lag gyi ;). Could have better example like DB connection class or something else.

[@shaikhgulab631]

Sir plz change themes

[@Abhishek-df5tf]

Yes

[@rajdippal51]

Please make a video how to create singleton pattern using enum

[@santoshhsah]

Hi Durgesh, There's a little mistake I think Each thread has its own stack, and different threads can have diff object values, I guess the instance datamember should be volatile.

[@syedfaizan5841]

[@souravpaul6086]

Hi, your videos are so informative I learned a lot from your videos thank you for making informative videos for us. I have a request could you please make a video where linkedin and twitter used as social login platform instead of github and google that can be very useful. Please make a video on this topic

[@khansamar6889]

Interview mein design pattern ke bare mein bahot puchte hai

[@Abhishek-df5tf]

Please use eclipse and change theam

[@lets_crack.]

After singleton design pattern there is no video uploading yet.As soon as possible plz share us.😊

[@ajinkyajadhav7665]

hello sir plz make a video on mockito test cases

[@geopluse6336]

sir video dhekke bhuk laggaya

theme name pls

[@rohitjaiswal946]

In Samosa, we are checking if(Samosa==null) and then creating an object, whereas in the case of Jalebi we are creating new object every time the get method called. So my question is why can't we remove the 'if check' in Samosa(I tried but it print different hashCode. Please help me anyone, I am new to Java and need some understanding.

[@krishnarai9843]

if we remove the if condition after that when we call the method it create new object every time in heap so, because of that your hash code always different. if we don't remove the if condition at first time it create object because there is null in samosa variable and after that it always give the that object which is store in samosa variable

[@Abhishek-df5tf]

Sir I request u Please Change theme
