If your codebase still has “data-only” classes filled with ctors, getters, equals/hashCode, and toString, it’s time to modernize.
With Records (JEP 395, Java 16+), you declare the state, and Java gives you the API:
✍️ One-liner declarations for immutable data
🧠 Auto-generated accessors, equals, hashCode, toString
✅ Validation/normalization via canonical or compact constructors
🏷️ Component annotations propagate to fields/ctors/accessors
🤝 Plays beautifully with sealed hierarchies & pattern matching for switch
