[Bluej-discuss] Chapter 7 zuul bad - HashMap cannot find symbol

[ric104]

Hi

I am on chapter 7 and trying to implement the HashMap as instructed by the
book, but I am getting
a "cannot find symbol" error,

I am making sure HashMap is avaiable by putting

import java.util.HashMap;

at the top of the page

But when it gets to this part it does not work and I get the "cannot find
symbol" error

(Iterator iter = keys.iterator(); iter.hasNext(); )

I am lost as to what to do and would appreciate some advice

Many Thanks
