Re: Newbie: Forced to cast when I don't think I need too

Greetings,
Not sure what etiquette is when post code snippets, but here I go;
Given the following 3 classes;
TestDriver
Customer
Center
Note not all methods currently implemented. Feel free to comment on
any nasty programming as I want to learn the correct way to code java
(old procedural programmer!).
Question: In my TestDriver class when I list out the various
CenterId's assigned to a Customer I have to cast it back to a center
before the IDE shows me the method get_CenterId() isn't there a way
for me to get at the get_CenterId() by using the result directly,
something like;
System.out.println("Center ID:" + (Center)i.next().get_CenterId());
The 3 classes follow;
package com.harless.remoteaccess;
import java.util.Calendar;
import java.util.ArrayList;
import java.util.Iterator;
public class TestDriver
{
public static void main(String[] args)
{
////////////////////////////////////////////////////
// assign some objects
////////////////////////////////////////////////////
Customer myCustomer = new Customer();
myCustomer.set_CompanyName("Anasazi Software");
myCustomer.set_StartDate("2008-01-01");
myCustomer.set_EndDate("2100-12-31");
myCustomer.set_CustomerCenter("PHX");
myCustomer.set_CustomerCenter("PHX1");
////////////////////////////////////////////////////
// print some objects
////////////////////////////////////////////////////
listCustomer(myCustomer);
}
