    In the interest of completeness ...

    public class LinkedProperties extends Properties {

    private final LinkedHashSet keys = new LinkedHashSet();

    @Override
    public Enumeration propertyNames() {
        return Collections.enumeration(keys);
    }

    @Override
    public synchronized Enumeration elements() {
        return Collections.enumeration(keys);
    }

    public Enumeration keys() {
        return Collections.enumeration(keys);
    }

    public Object put(Object key, Object value) {
        keys.add(key);
        return super.put(key, value);
    }

    @Override
    public synchronized Object remove(Object key) {
        keys.remove(key);
        return super.remove(key);
    }

    @Override
    public synchronized void clear() {
        keys.clear();
        super.clear();
    }
}



    I dont think the methods returning set should be overridden as a set by definition does not maintain insertion order
