Please assist. I'm writting a user defined method called getIterator
which returns an object that implement the standard java.util.Iterator interface. getIterator is not a method that you would find in the standard java.util.Map interface.
public java.util.Iterator getIterator( )
{ /* Implementation not shown */ }
private class LocalIterator implements java.util.Iterator
{/* next and hasNext not shown */
