I have the files in an arraylist. How would I get them from the arraylist into the code below, this first section, is the bottom section of the code following it.



 public void add(String fileName) {
        listOfFiles.add(fileName);
    }


public class ListOfFiles implements Enumeration {

    private List listOfFiles = new ArrayList(); // Start with an empty list by default
    private int current = 0;

    public ListOfFiles() {
    }
    public ListOfFiles(List listOfFiles) {
        this.listOfFiles = listOfFiles;
    }

    public boolean hasMoreElements() {
        if (current < listOfFiles.size())
            return true;
        else
            return false;
    }

    public Object nextElement() {
        InputStream in = null;
        if (!hasMoreElements())
            throw new NoSuchElementException("No more files.");
        else {
            String nextElement = (String)listOfFiles.get(current);
            current++;
            try {
                in = new FileInputStream(nextElement);
            } catch (FileNotFoundException e) {
                System.err.println("ListOfFiles: Can't open " + nextElement);
            }
        }
        return in;
    }

    public void add(String fileName) {
        listOfFiles.add(fileName);
    }
}

objects I really like the way you approach your code writing, direct but simple. I hope I learn from your example.
