Java: Check if enum contains a given string?

Question

Here\'s my problem - I\'m looking for (if it even exists) the enum equivalent of ArrayList.contains();.

Here\'s a sample of my code problem:

<

I don't think there is, but you can do something like this:

enum choices {a1, a2, b1, b2};

public static boolean exists(choices choice) {
   for(choice aChoice : choices.values()) {
      if(aChoice == choice) {
         return true;
      }
   }
   return false;
}

Edit:

Please see Richard's version of this as it is more appropriate as this won't work unless you convert it to use Strings, which Richards does.
