AbstractEnum._ordinal

The ordinal of this enumeration constant (its position in the enum declaration, where the initial constant is assigned an ordinal of zero).

Most programmers will have no use for this field. It is designed for use by sophisticated enum-based data structures, such as {@link java.util.EnumSet} and {@link java.util.EnumMap}.
