Package
Synopsis
This class represents a Java package.
You can obtain the Package
object for a given
Class
by calling the getPackage(
)
method of the Class
object. The static
Package.getPackage( )
method returns a
Package
object for the named package, if any such
package has been loaded by the current class loader. Similarly, the
static Package.getPackages( )
returns all
Package
objects that have been loaded by the
current class loader. Note that a Package
object
is not defined unless at least one class has been loaded from that
package. Although you can obtain the Package
of a
given Class
, you cannot obtain an array of
Class
objects contained in a specified
Package
.
If the classes that comprise a package
are contained in a JAR file that has the appropriate attributes set
in its manifest file, the Package
object allows
you to query the title, vendor, and
version of
both the package specification and the package implementation; all
six values are strings. The specification version string has a
special format. It consists of one or more integers, separated from
each other by periods. Each integer can have leading zeros, but is
not considered an octal digit. Increasing numbers indicate later
versions. The isCompatibleWith( )
method calls
getSpecificationVersion(
)
to obtain the specification version and
compares it with the version string supplied as an argument. If the
package-specification version is the same as or greater than the
specified string, isCompatibleWith( )
returns ...
