Who can do this?

Question

Hi
The code below prints this out
[goods out, firstname, lastname]
[id, adress1]
[country, phone]
[goods in]
Now how can i get my code to print out the same, but instead of using the strings Values and keys,
use hashtables?
Also how can i do it without using the (public static void getval)
Hope You can solve this
thanks

        String keys[] = {
            "firstname", "lastname", "id", "adress1",  "phone",
            "county",  "post code", "country", "goods in", "goods out"
        };//System.out.println(keys);
        String values[] = {
            "ben", "ben", "alex", "alex", "matt",
            "matt", "mum", "mum", "dad", "ben"
        // First, map keys to values in a hashtable
        Hashtable hash = new Hashtable();
        // the code matches values one by one for each of the keys
        for(int i = 0; i < keys.length; i++)
            hash.put(keys, values[i]);
// Then we find each value and remove it from the hashtable
for(int j = 0; j < values.length; j++)
          getval(values[j],hash);
// This will also print it to the screen
     private static void getval(Object value, Hashtable ht ){
          ArrayList arr = new ArrayList();
if( ht.containsValue( value ))
Enumeration e = ht.keys();
while (e.hasMoreElements())
String tempkey = (String)e.nextElement();
String tempvalue = (String)ht.get(tempkey);
if (tempvalue.equals(value))
               arr.add(tempkey);
ht.remove(tempkey);
}System.out.println(arr);
