JDK-8073381 - need API to get enum's values without creating a new array
Description
A DESCRIPTION OF THE REQUEST :
 
one needs a function that can translate from a <int> into the particular enum value...


JUSTIFICATION :
when one is developing one the wire protocols... one needs to be able to translate from a one the wire <int> back to a enum value... currently the only way to do that is to have
a switch statement

switch( aValue )
  {
   case 0:
       {
       theENUM = ENUM_0;
        break;
       }// end case 0

one has to do that for every Enum which makes them hard to work with...

EVALUATION Use the static method of any enum class: MyEnum.values()[aValue] The method isn't defined in java.lang.Enum, but you can see it in the javadoc of any enum class. ###@###.### 2005-03-01 17:17:47 GMT
