A
reference to the package name used with the Packages keyword:

where
JavaPackage is the name of the object's Java package. If the
package is in the java, netscape, or
sun
packages, the Packages keyword is
optional.
Description
In Java, a
package is a collection of Java classes or other Java packages. For
example, the netscape package contains
the package netscape.javascript; the
netscape.javascript
package contains the classes JSObject and
JSException.
In
JavaScript, a JavaPackage is a
reference to a Java package. For example, a reference to
netscape
is a JavaPackage.
netscape.javascript
is both a JavaPackage and a
property of the netscape
JavaPackage.
A
JavaClass
object is a reference to one of the classes in a package, such as
netscape.javascript.JSObject.
The JavaPackage and
JavaClass
hierarchy reflect the Java package and class hierarchy.
Although
the packages and classes contained in a JavaPackage are its
properties, you cannot use a for...in statement to
enumerate them as you can enumerate the properties of other objects.
Property Summary
The
properties of a JavaPackage are the
JavaClass
objects and any other JavaPackage objects it
contains.
Examples
Suppose
the Redwood corporation uses the Java redwood package to
contain various Java classes that it implements. The following code
creates the JavaPackage
red:
var
red = Packages.redwood
