An enum, short for enumerated type, is a variable type that can only take on the values that are declared inside the enum declaration. An enum is declared like a class, except the word "class" is replaced by the word "enum", and the class body is replaced by a list of values that a variable of that type can take on. You can also include methods, instance variables, and constructors in an enum.
