A DESCRIPTION OF THE PROBLEM :
'm trying to transverse an ArrayList with a for..each loop, but an error was reported through Eclipse IDE:
can only iterate over an array or an instance of java.lang.Iterable. See Source code marked A.

In another instance it was noted that the for..each loop was returning an unexpected String results, notwithstanding that I have provided a toString() method for the superclass (Employee).


NOTES
1. According to the Java API for 1.6, ArrayList implements Iterable<E> - http://download.oracle.com/javase/6/docs/api.
2. Java Notes, For-each loop at http://leepoint.net/notes-java/flow/loops/foreach.html.
