Iteration problem

Question

I have a list. It may or may not contain elements. I want to iterate through the list and where the element is not equal to null, cast it to a string and print it out to the screen.
There are two problems i get with my code, 1 is it doesn't read the first element and secondly i get a java.util.NoSuchElementException.
Anyone got any ideas?
Iterator iter = factList.iterator();
if(iter.hasNext())
     while(list.contains((String)iter.next()))
          content = (String)iter.next();
          System.out.println(content);
}

LinkedList is a little confusing because it also implements Queue.
The following are all pretty similar:
Object a = l.get(0);
Object a = l.getFirst();
Object a = l.peek();
Object a = l.element();The all return the first element, none alter l. (One difference is that some
of them have a runtime exception if l is empty!)
You ask "would that assign then remove". I'm not sure what you are
trying to say, but I think you should write a short example program a
try out a few things to find out how these methods work yourself.
It will only take a few minutes and you'll learn more than posting
questions on these forums. Save the forums for questions when you
are stuck.
