forEach in Java class

[Dan Parsons]

I have a JSTL forEach example that I would like to implement in a Java class instead of JSP.
Example:

Java class:
ArrayList<MovieBean> movies = New ArrayList<MovieBean> (MovieListing.getList());
request.setAttribute(movies, "movies"); 

JSP:
<c:forEach var="movie" items="${movies}">   
   ${movie} <br>   
</c:forEach>

Is the below attempt the right way?

Java class:
ArrayList<MovieBean> movies = New ArrayList<MovieBean> (MovieListing.getList());

for (Iterator it = movies.iterator(); it.hasNext(); ) 
{
    String movies = (String)it.next();
}

request.setAttribute(movies, "movies");

Does it work? Seems like that'd be the absolute quickest way of finding out, considering you've already written a first attempt.

It's not entirely clear what you're trying to do, though; right now it looks like you're setting each movie to a string, then doing nothing with it.

Note that if you're using Java 1.5+ you may want to consider using the loop syntax introduced there.

There's no need to use an iterator when looping over a List. For example iterating over a List<Item> :

for (Item item : items) { ... }

Dan,

No .. it doesn't look correct ... a couple questions ...

1. What does MovieListing.getList() return? a java.util.ArrayList of Strings, a java.util.ArrayList of MovieBeans or something else?
2. It looks like your JSP code places an ArrayList of MovieBean into scope and the toString() method of MovieBean prints what you want when you iterate using forEach. Is this what you want?
3. What do you want the Java code to do?

Its not working and seems to print all the records per array.
Its suppose to print a Java java.util.ArrayList of MovieBeans.

You have not posted your updated code since my post. What's the status of things now?
