Spring Tips: Data Oriented Programming in Java 21+

Hi, Spring fans! In this installment, we look at Java 21 and later's support for data oriented programming
code is available here: github.com/spring-tips/data-o...

Nice information. Thank you!

The moment he talks, I went to check whether I set the speed to 1.5x lol

[@die_p]

I set it to 0.85x to be able to follow without needing to rewind :)

I don't think there is any point in showing "my favorite place" selections in 0,1 sec. Same on and on. I was hoping that there were some code and examples in git. Nothing.

I do understand that these videos are just marketing material. And Josh is marvellous marketing and sales person. But please !?!

@@jootuubanen7727try Data Oriented Programming in Java 1.1 by Nikolai Parlog?

[@selimhorri7816]

Yeah regarding the "withers", i think they planning to add it very soon (i hope), something like :
UnsecuredLoan usl = oldUsl with {/*init specific variables*/};
Which means make a copy of oldUsl and make your changement in the body of the wither..
Cannot wait to see it in action, it will help alott..

they have it as preview JEP 468: Derived Record Creation

[@dennisveltropgmail]

For now I use Lombok

[@epsig1507]

11:03 they have that in JEP 468 (Derived Record Creation)

please improve the audio quality (microphone!)

[@henryvaneyk3769]

Just some advice. Firstly get a lapel microphone to capture your voice much better. Secondly, get some acoustic dampening materials in the room where you do your recording. It is very difficult to hear clearly what you are saying.

Hi Josh - which MacBook you are using 16” or 14” , can you please share the specs ?

[@tobyzieglerrr]

sealed interface permits implA, implB
This still hurts me. Of course it can be useful, but it defends the purpose of interfaces.
Why should an interface ever know which implementors it has. There are examples, i know them,
but this still looks to me like a serious "avoid" in a large code base.

Might be the best dev ever, but the communication makes this video hard to watch.
