Using Record Types to Build Better Domain Models
summary
Covers Java Records (introduced in Java 14) and the move toward true value types: the record syntax, differences between reference and value types, and how value types affect immutability, readability, and performance (stack vs heap storage). Compares value-type implementations in other languages, discusses inheritance implications for value types, and argues how using value types leads to better domain models and fewer failures.
