That works for classes that only provide services, but not for classes that create data transfer objects; you can't save multiple sets of data in one set of class variables. For the same reason, if a class needs to save multiple configurations, it needs to produce configurable objects. I hope that helps.
Oh Man!!!! just in a matter of few minutes I actually understood the significance of Singleton approach. As the example you gave in regards to AccountService Class. I used to ask many people about actual real-time use of Singleton pattern in java application. I got the essence today. you are just marvelous. Thanks! a lot.
I would also like to request that you make a video or a series of videos on spring security. Your tutorials are much better than other ones online and I think that would be a good topic
This was presented very well. My work has been trying to get me to learn spring but the material they gave me was a muddled mess. You have given me a much better conceptual understanding.
A friend recommended your spring playlist and they've been very helpful in filling in the knowledge gap while I use SpringBoot and SpringSecurity at a java web dev boot camp. Thank so much! - Jen
I like the way how u deal with concepts in a practical manner. I'm not even watched of the video yet, and I couldn't resist hitting like button for the way u explained the dependency injection without actually using the term itself... please don't stop making videos bro.. thanks a ton!
I think you're slowly making me not have java with your simple explanation. You've just summed up a 4h lecture in a much more memorable and useful way.
Awesome video. I was told to learn spring MVC by somebody but I never really understood what its all about and why I needed it in the first place. This video has made everything very clear now!
hey Koushik you made a video on java learning path, and emphisized on how core java is so important now i am wondering why you do not have a core java tutorials on your channel, you would really make a lifetime tutorials for this important aspect.
Apart from learning the content, i think one should learn how to really express and break down a concept and explain it like you do. I have never seen a spring explanation that doesnt bring in the jargons of DI, IOC until as late as 7th minute, exactly what i was looking for. That really helped thanks.
I second this. Spring Security I feel is one of the most complicated modules in Spring Framework which has less tutorials online. It would be great to have a good series of tutorials that talk about this in depth including how to connect with various datastores like sql, nosql, ldap, active directory etc. Also various protocols like basic auth, oauth2, open id connect etc.
Former SpringSource developer here. If you're going to explain Spring as providing these features: 1. Application context and dependency injection 2. Data access 3. Spring MVC ... then you also need to explain that these are separate modules from which you can pick and choose. Spring hasn't been a monolithic JAR since 2.5.6, which is maybe 15 years ago. Unfortunately the myth of Spring being "bloated" has persisted long after it ceased to be true.
Nice video, thanks, but I’ve always wondered why you need an instance? Why not just static methods for services?
Good question! Static methods are difficult to test and mock, so are generally avoided.
That works for classes that only provide services, but not for classes that create data transfer objects; you can't save multiple sets of data in one set of class variables. For the same reason, if a class needs to save multiple configurations, it needs to produce configurable objects. I hope that helps.
@@jpnoyola whats the problem when static methods creat DTO
static concept destroys object oriented programming. that's why scala and kotlin don't use static but singleton object.
Overriding is not possible
1. Managing objects & Lifecycle dependencies by providing
Application context and dependency injection
2. Data access
3. Spring MVC
SPOILER WARNING!
Please do not stop creating Videos. Your teaching is very very useful for us.
Finally... someone who ACTUALLY explains what spring does in a simple way!! Thanks heaps!
Every time a have a question on any Java topic, I come to your channel looking for answers, thanks a lot.

Love Spring framework, I think I have not seen a more simple and clean explanation like this, Thanks for this video.
Thank you Sir by studying your tutorials of Rest and Spring I cracked the Java interviews of many companies.
Thank You very much
May God Bless You
I have finally found a description of what Spring is and why it is useful.
This was the thing I needed for the entire day ! What spring is actually about ? I got a very intuitive answer from this video. Thanks so much.
This is such a great video. Thank you for all the effort you put into making these.
This was presented very well. My work has been trying to get me to learn spring but the material they gave me was a muddled mess. You have given me a much better conceptual understanding.
You're the only one who can explain Spring framework well
Great teacher. Thanks for sharing your knowledge and teaching talent!
Koushik.. really a great admirer of your tutorials.Could you please videos on Spring Security especially OAuth2.0 and JWT.
Father of Java tutorials is back.
Where is a mother?

Boss is back get ready.
Father of Java. like ur teaching style. from bangladesh
Thanks very much!
Your old video just helped me understand what I'm learning exactly at school.
Great job sir. Appreciate your good work. 👏 Been trying to understand spring and by far this is the best explanation.
I just found your channel today and your videos/explanations are some of the best I have seen! Very excited about it :)
Thank you a lot! I'm starting to learn Spring Boot but i wanted to get a clear image on what Spring is all about.

Thank you, a very easy and positive way of reaching out when you want to learn something new, very good! Please continue with it!

I owe so much of my knowledge and understanding to you, thank you.
Hi asmaa can we study together im looking for few study prtners

Excellent explanation. One of the clearest. Thanks!
Excellent introduction to the Spring framework!
The Bosssssss is back... 🤩🤩
Really good video with clear explanations!
Clear breakdown and explanations, great stuff.
Very informative , well delivered, interesting video. I learned a lot and got better understanding of it.Thank you.
Wah bete wah! Moj Kardi!

Thank you man, you saved my nerves understanding what it is all about
Your way of presentation is hats off..
Very good and clear explanations. Thumbs up!
explanation is good and it is in understanding nature...thank you java brains
Thanks for video, now I better understand, what spring do.
I gave you a thumb up when I red to dependency injection... first video to explain greatly
YOU are one of the BEST PRESENTERS I've come across since Al Gore INVENTED The Internet ;-) --- KEEP MAKING VIDEOS !!!
Quality video. Clarifies the advantages of spring framework.
Thank you for direct to the point video!
Love your videos! Need make schedule to watch all your videos
Thank you for this very useful video!
Please make video on spring security and server side data validation
I second this. Spring Security I feel is one of the most complicated modules in Spring Framework which has less tutorials online. It would be great to have a good series of tutorials that talk about this in depth including how to connect with various datastores like sql, nosql, ldap, active directory etc. Also various protocols like basic auth, oauth2, open id connect etc.

Former SpringSource developer here. If you're going to explain Spring as providing these features:

... then you also need to explain that these are separate modules from which you can pick and choose. Spring hasn't been a monolithic JAR since 2.5.6, which is maybe 15 years ago. Unfortunately the myth of Spring being "bloated" has persisted long after it ceased to be true.
I don't think he must explain about the separation of these features.
