I've seen two approaches to handling enums with properties. Is one better than the other?
As a property:
public enum SEARCH_ENGINE {
GOOGLE("http://www.google.com"),
BING("http://www.bing.com");

I'm enumerating over a collection that implements IList, and during the enumeration I am modifying the collection. I get the error, "Collection was modified; enumeration operation may not execute."

I am attempting to find a way to force Java to load/initialize an enumerated type (which is nested within a class that contains a static Map).
This is important to me because the enumerated type has a constructor that populates said map, and without…
I would like to iterate through a CFDictionary (CFPropertyList) and get all values on a specific level.
This would be my dictionary / property-list:
root
A
foo
0
bar
0
B
foo
10
bar
100

Considering such an enumeration :
type
TTypeOfData = (
[XmlName('ABC')] todABC,
[XmlName('DEF')] todDEF,
[XmlName('GHI')] todGHI
);
Where XmlName is a custom attribute used to define the serialization string for members of this…
If I had the value : "dog" and the enumeration:
public enum Animals
{
dog = 0 ,

EDIT:
I am wondering if there is index like acces. More commonn : how can I get the…
I know this is typically a bad practice but in my case it is necessary.
I have a case where an Enum holds a class to gain some information. So that Enum creates an instance of that calss in its Constructor.

A developer at work recently started using a class pattern instead of enums in places where enums would usually fit. Instead, he uses something similar to that below:
internal class Suit
{
public static readonly Suit Hearts = new Suit();

When i have a code block
static void Main()

First of all I found two useful articles in documentations about these methods:

How do I make a generic enum rotator? It would be a generic version of next() in this example.
public class TestEnum

I'm wondering if you can extend already existing enumerations in Scala. For example:
object BasicAnimal extends Enumeration{
type BasicAnimal = Value
val Cat, Dog = Value
}
Can this be extended something like this:

I was trying my hands on vectors and wrote a simple code to access its elements through enumeration.
Vector v = new Vector();
v.add("Some String");
v.add(10);
Enumeration e = v.elements();
while(e.hasMoreElements())…
