Implementing the interface java.util.Enumeration passing the object
with JavaScript implementation directly to the constructor.
This is a shorthand for JavaAdapter constructor:

elements = new JavaAdapter(java.util.Enumeration, {
        index: 0, 
        elements: array,
	hasMoreElements: function ...
        nextElement: function ...
		});
 */

// an array to enumerate.
var array = [0, 1, 2];

// create an array enumeration.
var elements = new java.util.Enumeration({
        index: 0,
        elements: array,
        hasMoreElements: function() {
                return (this.index < this.elements.length);
	},      
        nextElement: function() {
                return this.elements[this.index++];
	}
    });

// now print out the array by enumerating through the Enumeration
while (elements.hasMoreElements())
	print(elements.nextElement());
