16.3. The
Modifier
Class
The
Modifier
class defines
int
constants for all non-annotation modifiers:
ABSTRACT
,
FINAL
,
INTERFACE
,
NATIVE
,
PRIVATE
,
PROTECTED
,
PUBLIC
,
STATIC
,
STRICT
,
SYNCHRONIZED
,
TRANSIENT
, and
VOLATILE
. For each constant there is a cor-
responding query method
is
Mod
(intmodifiers)
that returns
TRue
if modifier
mod
is present in the specified value. For example, if a field is declared
public static final int OAK = 0;
the value returned by its
Field
object's
getModifiers
method would be
Modifier.PUBLIC | Modifier.STATIC | Modifier.FINAL
The
strictfp
modifier is reflected by the constant
STRICT
. If code or a
class is to be evaluated in strict floating point (see "
Strict and Non-Strict
Floating-Point Arithmetic
"
on page
203
)
, the modifiers for the method,
class, or interface will include the
STRICT
flag.
The query methods can be used to ask questions in a more symbolic
fashion. For example, the expression
Modifier.isPrivate(field.getModifiers())
is equivalent to the more opaque expression
(field.getModifiers() & Modifier.PRIVATE) != 0
