Kotlin Enums

Using Enums

Kotlin enums define constants with properties and methods.

Introduction to Kotlin Enums

Kotlin provides a powerful way to define a set of related constants through enums. Enums, short for enumerations, are a special class type that represents a collection of constants. Each constant in an enum is an object that can have properties and methods. This capability allows developers to manage and utilize these constants effectively in their applications.

Defining Enums in Kotlin

In Kotlin, you define an enum using the enum class keyword. Each enum constant is a separate instance of the enum class. Here's a basic example of defining an enum:

Adding Properties and Methods to Enums

Enums in Kotlin can also have properties and methods. This allows each constant to hold additional data or perform specific actions. Here's how you can add properties and methods to enums:

Using Enums with When Expressions

Kotlin's when expression is a powerful tool for working with enums. It allows you to execute code based on the enum value. Here's an example of using enums in a when expression:

Iterating Over Enum Constants

In Kotlin, you can easily iterate over all the constants of an enum using the values() function. This can be useful when you need to perform an action on each constant. Here's how you can iterate over the constants:

Conclusion

Kotlin enums are a powerful feature that allows you to define a set of constants with additional properties and methods. They can be used effectively within when expressions and iterated over with ease. Experimenting with enums in Kotlin can help improve the structure and readability of your code.
