Java for the Data Model

The languages that I'm studying now have a focus on immutable data structures. Is that what you would call a value object? Yeah, sure. It's like representing domain concepts that are values and that allow you to perform with certain, like, I'm not business operations, but again, speak the language of the business. There's more ceremony maybe in Java for the data model. Right. You get that you actually just use the type system to express domain concepts.
