More enum confusion

[Eric Smith]

The documentation for the Enum method ordinal() states "Most programmers
will have no use for this method." Since I can't use an enum constant
directly as an array index (which seems like a huge oversight), how else
would I use it for indexing *other* than getting the ordinal?

Thanks,
Eric

Forget (reference) arrays. They are broken.

Use java.util.EnumMap.
