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 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.

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
