How to get the enum type by its attribute?

by

Apart from the issues pointed at by the other posters, I’d rewrite the method to avoid duplicating the information (keep it DRY!):

public static AreaCode area(int n) {
  for (AreaCode c : values()) {
    if (c.ac == n) {
      return c;
    }
  }
  // either throw the IAE or return null, your choice.
  throw new IllegalArgumentException(String.valueOf(n));
}
