What is Singleton Class in Java | Singleton Design Pattern Part 1

Thanks

I awe you respect Sir,Can't thank you enough.🙏🏻
I never understood why do we use a private constructor in a singleton class ,when jvm has automatically a default public constructor defined.
Got the answer,: To make it private and not allow clients to make objs with default constructor which is public by default,i.e to simple restrict the user from creating instance of the class .
Greatful to you.🙏🏻🫡🙏🏻❣️💯

Thanks for explaining this topic so simply.

And, if the singleton needs to call a web service to fetch some values, where do you place the code? Do you place it inside the singleton class or outside?

lot of videos in java. why not in python?

We can also remove the getInstace method and can directly call the object by writing (Abc obj1 = Abc.obj) in main method

Amazing 🙏🙏🙏

Concise as always!

you are amazing sir.

thx!

Bro y cant we use static class abc
Insted of declaring an static abc object

That;s the reason i love navin reddy tutorials he will just make viewers master in the concept what he is teaching Great man u are really great ALIEN..

Thanks, I wish I came straight to this post before searching around; you made this concept very easy to understand.

Very nice explanation sir. Keep making this type of valuable video always.
Thanks a lot

Great video. Short and to the point. Good explanations.

excellent tutorial, thank you so much, easy to understand!

nice and clear explanation

Either i am stupid or something is wrong here ! how on earth he is able to create a method (getInstance) without mentioning the return type ? I mean i am not able to do that my IDE shows error

Simple and Amazing explanation!

Great explanation

Thank you. Guys please like and share his videos. He really works hard. Thank you sir thank you so much.

Thank you a lot 💫

Hey! Is possible to pass arguments in singleton

Thanks. This is amazing explanation. Easy to understand!

Singleton grindset

Just adding some information here because I was facing the issue. We can create as many as instances inside the class because in the class we can access private constructor but we can't access it from outside the class.

is this singleton tutorial or simpleton trying speak English

Today I was asked this question in Java Back End Developer interview for Qualitest.

Best explanation of this. Saved me a whole lot of trouble and inefficient alternatives

Why there is not setter but getter in singleton class

this is the most simple explanation of a singleton design pattern i ever came across, thanks a lot

great video

Best explanation have ever found... thank you:)

i have a doubt, every time calling the getInstance() there is new instance of Abc class will create, so then how this approach follows singleton design pattern?

Nice Explanation of Singleton :)

Thanks Naveen! for making java interesting

Thankyou for thIs beautiful explanation.. could you also includes the implementation of such concepts in a project

I agree with some of the comments here. The explanation is really good but an example would have helped a lot.

One example for Singleton use is simply Database connections. You don't want more than one instance throughout the application.

Thank you

I have a question. We could have called the static variable in the other class main method, would have acted the same way as it is a static variable itself. Why we need a static method and call the static variable through the method?

best explanation about Singleton Class

Awesome explaination of single ton pattern

Thanks, sir. This really helps to get a proper understanding of the basics!

Thanks man! I have to make one of these for a project I'm working on. This is exactly what I needed to see.

Do we need the private constructor? Will it work without it?

🇿🇦🇿🇦🇿🇦🇿🇦🇿🇦🇿🇦🇿🇦🇿🇦🇿🇦🇿🇦, which country is this from the flag??

link of the code doesn't work.

mana telugollu eppudaina thope ehe.

What if we pass parameters while creating instance of class

clear cut to the point explanation
