The useExample ColdFusion page
The following useExample.cfm page uses the
Example
class to manipulate numbers, strings, Booleans, and Example
objects. The CFML JavaCast function ensures that CFML variables convert into the appropriate Java data types.

<!--- Create a reference to an Example object --->
<cfobject action=create type=java class=Example name=obj>
<!--- Create the object and initialize its public member to 5 --->
<cfset x=obj.init(JavaCast("int",5))>
<!--- Create an array and populate it with string values,
then use the Java object to reverse them. --->
<cfset myarray=ArrayNew(1)>
<cfset myarray[1]="First">
<cfset myarray[2]="Second">
<cfset myarray[3]="Third">
<cfset ra=obj.ReverseStringArray(myarray)>
<!--- Display the results --->
