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
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.
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.
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!
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!
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.
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.
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!
Love Spring framework, I think I have not seen a more simple and clean explanation like this, Thanks for this video.
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
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
Every time a have a question on any Java topic, I come to your channel looking for answers, thanks a lot.
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 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.
Koushik.. really a great admirer of your tutorials.Could you please videos on Spring Security especially OAuth2.0 and JWT.

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.
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 gave you a thumb up when I red to dependency injection... first video to explain greatly
Father of Java tutorials is back.
Where is a mother?

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.
Thanks very much!
Your old video just helped me understand what I'm learning exactly at school.

Clear breakdown and explanations, great stuff.
Please make video on spring security and server side data validation
