How can I make my class iterable so I can use foreach syntax?

Question

I have Book and BookList classes. BookList is something like this:

public class BookList 
{
    private final List<         


        

Answer 1

To be more specific about how to "implement the Iterable interface":

public class BookList implements Iterable
{
    private final List bList = new ArrayList();

    ... 

    @Override
    public Iterator iterator()
    {
        return bList.iterator();
    }
}
