 ## Conclusion
 
-Enums provide a simple and safe way of representing a fixed set of constants while keeping most of the flexibilities of classes. They are a special type of class that can be used to write code that is elegant, readable, and maintainable, and work well with other newer modern features like [Switch Expressions](id:lang.basics.switch_expressions). Another special class is the Record class introduced in Java 19. Visit our [Records tutorial](id:lang.records) to learn more.
