Hey
That totally makes sense, and I definitely see hot to iterate through
a collection of Strings or other straightforward things, but what I'm
confused about is that my PortfolioBeanCollection (extends ArrayList)
contains objects of type "PortfolioBean" which in turn contain the
attribute I'm trying to display..so the PortfolioBean itself has no
explicit name to which I can refer...
so I really want to do something like
PortfolioBeanCollection.PortfolioBean.portfolioName
normally, I'd just loop through the PortfolioBeanCollection casting
the resulting Object into a PortfolioBean then calling the
getPortfolioName() method on the bean
The examples I'be found deal more with simple Collections of Strings,
ints, etc. where you might have a collection of "teachers" for example
and want to print out the firstName attribute of each... whereas my
example has another later.
I might be babbling. Does that make sense?
