In programming, sometimes, there are only specific values of a type; to complete this, the concept of enumeration was introduced. Enumeration is a list of constants.
In Kotlin, like many other programming languages, Enum has its specific type, indicating some possible values. Kotlin enums are classes, unlike java classes.
There are some essential points about Enum Classes:
Kotlin also has a constructor similar to Java items. Since enum constants are examples of an Enum class, constants can be started by transferring specific values to the primary constructor.
As in Java and other programming languages, Kotlin enum classes have built-in properties that programmers can use. Here are the key features and methods.
From the enum class in Kotlin, a new type is defined. This class type may have its features and functions.
Properties can be given a default value; however, if not specified, each constant must define its value for the property.
In terms of functions, they are usually defined within companion objects, so they do not depend on the specific context of the class. However, it can be defined without companion objects.
As well as overcoming the abstract functions of the class and implementing their functions, the constant also acts as an anonymous class. The most important thing is to override each Enum constant.
A significant advantage of Kotlin's enum classes is that they work when combined with expression. Because enum classes limit the value that one type can take, when expressions and definitions are given for all constants, the need for other clauses is eliminated. Performing this task will generate a warning from the compiler.
