Better Modeling Through Records
summary
Introduces Java's new record classes (the record keyword) as a concise way to define immutable data carriers, with the compiler generating boilerplate like constructors, equals, and hashCode. Argues the purpose of records is not just reducing typing or imitating Lombok/@Data, but enabling better domain modeling and safer, more concurrent-friendly designs, similar to records in C# and data structures in Scala/Kotlin.
