    Default Collection to JList to Display

    Just wondering why when i use this which should correctly get a collection turn it to array then let me turn it into a JList and display it. why it lets me compile it fine but just displays a empty box. does this if i use either the dept or entry array in the JList

    Java Code:
    Collection<Department> d = Department.getCollection();
    dept = new Department[d.size()];
    String[] entry = new String[dept.length];
    for (Iterator<Department> iter = d.iterator(); iter. hasNext(); )
    for (int k=0; k<dept.length; k++) {
    dept[k] = iter.next();
    entry[k] = dept[k].getName();
    }
    JList deptList = new JList(dept);
    deptList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
    panel.add(deptList);
    JScrollPane deptListscroll = new JScrollPane(deptList, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
    panel.add(deptListscroll);
    any Help appreciated

    Default

    Do you not want to use the "entry" array, rather than the "dept" array in the JList constructor call?
