JSTL - Using forEach to iterate over a user-defined class [duplicate]

Answer 1

The Iterable interface provides this functionality:

public class ProjectSet implements Iterable {
    private ArrayList projects;
    public ProjectSet() {
        this.projects = new ArrayList();
    }

    // .. iteration methods ??
   @Override
   public Iterator iterator() {
       return projects.iterator();
   }
}

You can exchange the iterator logic as you need.
