I am inserting some values in hashtable. But its not keeping the order as i inserted.

 for (int i = 0; i < SignatureKey.size(); i++) {

               m.put(SignatureKey.elementAt(i), SignatureValue.elementAt(i));
    }

please suggest something.

By its nature a hash table should be an unordered collection. If you want to preserve the ordering of your elements, use a different data structure.

    One way would be to make a keypair class, and have a vector of those. [Take a look at this topic](http://stackoverflow.com/questions/521171/a-java-collection-of-value-pairs-tuples). – Alan Apr 04 '13 at 09:10
