Calling Java Objects 387
The useExample CFML Page
The following useExample.cfm page uses the Example class to manipulate numbers,
strings, Booleans, and Example objects. Note the use of the
JavaCast CFML function
to ensure 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 --->
<cfoutput>
<br>
original array element 1: #myarray[1]#<br>
original array element 2: #myarray[2]#<br>
original array element 3: #myarray[3]#<br>
after reverse element 1: #ra[1]#<br>
after reverse element 2: #ra[2]#<br>
after reverse element 3: #ra[3]#<br>
<br>
</cfoutput>
<!--- Use the Java object to flip a Boolean value, reverse a string,
add two integers, and add two float numbers --->
<cfset c=obj.Flip(true)>
<cfset StringVal=obj.ReverseString("This is a test")>
<cfset IntVal=obj.Add(JavaCast("int",20),JavaCast("int",30))>
<cfset FloatVal=obj.Add(JavaCast("float",2.56),JavaCast("float",3.51))>
<!--- Display the results --->
<cfoutput>
<br>
StringVal: #StringVal#<br>
IntVal: #IntVal#<br>
FloatVal: #FloatVal#<br>
<br>
</cfoutput>
