Java 14 Feature Spotlight: Records

Record are product types, with union types (sealed types in Java speak) you get algebraic data type, you can take a look to SML to understand why there will be used a lot.

Record have an automatic way to propagate annotations from the record component to the generated methods/fields and comes with native support of serialization (like enums).

Could you show an example of it? In none of the materials published so far there is anything even remotely similar to what you are suggesting.

There you can read about algebraic data types in java, in Java 14 you get preview for records in Java 15 probably you'll get preview for sealed types - they were developed together for some time, only recently there was a split.
