How to sort elements in Hashtable.

Question

I am adding elements in sorted order in Hashtable. But when I iterate through the Hashtable using 'Enumeration' on the keys the the elements are not fetched in sorted order. I want to retrieve the keys in sorted order. How can we fetch the keys on sorted order?
import java.util.* ;
public class temp
     public static void main(String [] abc)
          Hashtable hashList = new Hashtable();
          hashList.put("1","One");
          hashList.put("2","Two");
          hashList.put("33","Three");
          hashList.put("44","Four");
     Enumeration keys = hashList.keys();
     while(keys.hasMoreElements() )
                    System.out.println("Key: " + keys.nextElement());
Output for this is -
Key: 2
Key: 1
Key: 33
Key: 44

Answer 1

obtain a set view of the keys contained in this Hashtable and sort it.
