6.2.1. Enum Modifiers
An enum declaration can be preceded by certain modifiers:
annotations Annotations and annotation types are discussed in
Chapter 15 .
access modifiers Nested enum declarations can have any of the
access modifiers, while a top-level enum, as for a top-level class,
is either public or in the absence of an access modifier, accessible
only within its own package.
static All nested enums are implicitly static because they contain
static members. By convention, the static modifier is always
omitted.
strict floating point All floating-point arithmetic within an enum
declared to be strictfp is evaluated strictly. See Section 9.1.3 on
page 203 for details.
When multiple modifiers are applied to the same interface declaration,
we recommend using the order listed above.
An enum cannot be declared abstract because you cannot extend it to
provide missing method implementationshowever, an enum can declare
abstract methods. You'll shortly see how this apparent contradiction is
resolved.
An enum also cannot be explicitly declared final , though it acts as if it
were final. You'll shortly see why this is so, too.
