4.2.3. Interface Modifiers
An interface declaration can be preceded by interface modifiers:
•
annotations
Annotations and annotation types are discussed in
•
public
A
public
interface is publicly accessible. Without this modi-
fier an interface is only accessible within its own package.
•
abstract
All interfaces are implicitly
abstract
because their meth-
ods are all abstractthey have no implementation. Again, by con-
vention, the
abstract
modifier is always omitted.
•
strict floating point
An interface declared
strictfp
has all floating-
point arithmetic, defined within the interface, evaluated strictly.
This applies to initialization expressions for constants and to all
nested types declared in the interface. In contrast to classes,
this does not imply that each method in the interface is implicitly
strictfp
because that is an implementation detail. See
Section
When multiple modifiers are applied to the same interface declaration,
we recommend using the order listed above.
