protected Enum(String name, int ordinal)

- - The name of this enum constant, which is the identifier
used to declare it.ordinal
- - The ordinal of this enumeration constant (its position
in the enum declaration, where the initial constant is assigned
an ordinal of zero).Method Detail |

public final String name()
toString()
method in
preference to this one, as the toString method may return
a more user-friendly name. This method is designed primarily for
use in specialized situations where correctness depends on getting the
exact name, which will not vary from release to release.

CloneNotSupportedException
- if the object's class does not
