If you are not using J2SE 1.4 - OrderedMap - (maintains order of insertion)

Question

Hi,
If you are not using J2SE 1.4 and still want to maintain the order of insertion unlike HashMap or Hashtable(which doesn't allow)
OrderedMap comes to resue!
import java.util.ArrayList;
import java.util.List;
import java.util.TreeMap;
public final class OrderedMap extends TreeMap {
     private List list= new ArrayList();
     public OrderedMap() {
     public Object put(Object key, Object value) {
          list.add(key);
          return super.put(key, value);
     public List getKeysList() {
          return list;
};;Mail me how to use it!
Bye
