Joda-Beans VS jpa-entity-generator

That means I don't forget about fields (as can happen if you're just doing `person.setX()` all the time). It's easy to see what is what when reading it. I can delete fields I don't want to initialize at the time. Yes, maybe immutable objects are the One True Way, but C# lets me choose (I can label properties with an initializer `init` rather than a setter `set` and then they're immutable).

Kotlin offers stuff like this too because it's really useful toward creating code that's easy to create and maintain. Go also lets you initialize structs in a similar fashion.

Java has come back to us a decade or more late with records. They're not bad, but they're only offering one thing. They don't cover what C#, Kotlin, Go, and other languages have offered for so long.

The annoying thing about Java is that it doesn't feel pragmatic a lot of the time. It feels like the language hates stealing ideas from others. It's Java: people steal ideas from Java, not the other way around. People do crazy things just to get POJOs including Immutables (http://immutables.github.io), AutoValue (https://github.com/google/auto/), Lombok (https://projectlombok.org), Joda Beans (https://www.joda.org/joda-beans/), and maybe more. They generate lots of code at compile time or do funky runtime stuff.

It just feels like Java misses the pragmatic stuff and still kinda doesn't want to handle that. I feel a bit silly harping on things like POJOs and setting data on a new object, but that's a big part of day-to-day stuff and it definitely pushes users away from Java towards languages that seem "better" simply because they don't have Java's oddly strong attachment to not offering simple value objects. Yes, again, records do something - but it feels like Java ignored how people are using Kotlin, Go, C#, and more and didn't go for something that would have been as widely applicable and pragmatic as it could have been.

Java has a lot of great stuff like great GCs (yes), lots of cool research, great performance, and Project Loom is really exciting. I just wish the language would lean a little more practical.

I know I've been talking about properties a bunch, but let's look at Java. Java Beans are terrible - so terrible that the community has a number of workarounds. Immutables (https://immutables.github.io) lets you generate builders, Lombok (https://projectlombok.org) has their annotations that do runtime and IDE magic, there's Joda-Beans (https://www.joda.org/joda-beans/), there's the new Java Records if you want immutable-only and non-compatibility with lots of libraries, there are people using Kotlin for their data classes and Java for other things... Properties are this simple thing that lets C# work with the whole getter/setter pattern without being horribly annoying - there's just this weird { get; set; } thing that I can ignore because I don't care.

Want more examples? What about database schemas and mapping them to your ORM/other persistence layer solution? I think if you're writing your own model code, you're doing something wrong, regardless of the language that you use. You'll probably mess up or miss relation mapping with something like Hibernate, will miss out on some comments for autocomplete in Laravel and just generally will have an inconsistent persistence layer that will make you waste time.

In most cases, starting with the schema first and using one of the available generation solutions to fill in the application side of the persistence layer seems like the only sane options. Sure, some might prefer to handle migrations in the app side, like Ruby's Active Record Migrations, or something like Liquibase, which are also passable approaches, as long as you don't create a bad schema just so it fits your application.
