How to declare enums outside and inside the class ?

Enum outside the class

enum CoffeeSize { SMALL, MEDIUM, LARGE}

class Coffee {

     CoffeeSize size;

}

public class Test {

     public static void main(String[] args) {

         Coffee drink = new Coffee();

         drink.size = CoffeeSize.BIG; // enum outside class

     }

}

Enums inside the class

class Coffee2 {

     enum CoffeeSize {SMALL, MEDIUM, LARGE }

     CoffeeSize size;

}

public class CoffeeTest2 {

     public static void main(String[] args) {

          Coffee2 drink = new Coffee2();

          drink.size = Coffee2.CoffeeSize.BIG;

     }

}

Note:

 - Enums cannot be declared inside the methods.
 - Enums cannot be private or protected.

 - Semicolon is optional for enum, like :

  enum CoffeeSize {SMALL, MEDIUM, LARGE };
