Enums

[Sandeep Vaid]

In Kathy & Bert's book, page no 60 it's written that

Enums can be declared as their own seperate class, or as a class member

But the following 2 examples shows that enums can be declared outside the class or inside the class.

Hi,
"Enums can be declared as a separate class " means Enums can be declared like class declaration.

class A
{
}

similiarly

enum e
{
}

No i don't think so it means that. This is the basic enum declaration syntax no matter where you declare it.

I understand :

1. Enum can be declared outside all classes.

   enum E{E1,E2}
   class Temp
   {
    
   }

2. Enum can be declared in a class (its own class), however it's variable is declaerd in another class.

 
 class A
 {
   enum E{E1,E2}
 }   
 
 class B
 {
   A.E e1; 
 }
   

3. Enum along with it's variable (instance variable) can be part of a single class..

Class A
{
  enum E{E1,E2};
  E e1;
}
 
    

Let me know if i am correct.

I believe that the first and third of your three cases are those meant by K & B.

The second case is not wrong but it will not be seen very often.
