Kotlin Enumeration Class _kotlin

The most basic use of an enumeration class is to implement type-safe enumerations

Enum class Direction {North
    , SOUTH, West, East
}

Kotlin

Each enumerated constant is an object. Enumeration constants are separated by commas. Class

Because each enumeration is an instance of an enumeration class, they can be initialized.

Enum Class Color (Val rgb:int) {
        RED (0xff0000),
        GREEN (0x00ff00),
        BLUE (0x0000ff)
}

Kotlin Anonymous Class

Enumeration constants can also declare their own anonymous classes

Enum class Protocolstate {
    waiting {
        override fun signal () = Talking
    },

    talking {override
        fun sig NAL () = Waiting
    };

    Abstract Fun Signal (): Protocolstate
}

Kotlin

And the corresponding methods, and methods to override the base class. Note that if the enumeration class defines any
Members, to separate the enumeration constants in the member definition by using semicolons, as

The same in Java.
