Iterator in swing

Question

is it possible to use an iterator in the actionclass? im sure you are but for some reason i get the compile error:

symbol  : class Iterator
location: class SoftwareHouseFrame.ApplicationDisplayStaff
            Iterator iter = theSoftwareHouse.theStaff();
            ^

symbol  : method theStaff ()
location: class SoftwareHouse
            Iterator iter = theSoftwareHouse.theStaff();

2 errorsand no idea whats happening. I did import the java.util.* package
the code:
System.out.println("Display Staff");
//display the staff
SoftwareHouseFrame.this.theViewingArea.append("\n" + theSoftwareHouse);
SoftwareHouseFrame.this.theViewingArea.append("\n\t" + "Staff in the " + theSoftwareHouse);
boolean stafffound = false;
Iterator iter = theSoftwareHouse.getStaffIterator();
while(iter.hasNext() == true)
Programmer employee = (Programmer)iter.next();
//check size of iterator/container
SoftwareHouseFrame.this.theViewingArea.append("\n\t\t" + employee);
stafffound = true;
if(stafffound == false)
SoftwareHouseFrame.this.theViewingArea.append("\n\tNo Staff");
