This article introduces you to the difference between enumerated types and typesafe enums. You will learn how to declare a typesafe enum and use it in a switch statement, and you’ll see how to customize a typesafe enum by adding data and behaviors. We’ll also take a look at java.lang.Enum<E extends Enum<E>>, which is the base class for all typesafe enums.
