Enum type

Enum is a type with a restricted set of constants values. Here is an example, as follows:

pragma solidity ^0.4.24;  contract ColorEnum {    enum Color {RED,ORANGE,YELLOW, GREEN}    Color color;    function construct() public {     color = Color.RED;    }    function setColor(uint _value) public {      color = Color(_value);    }  function getColor() public view returns (uint){      return uint(color);  }}
