Mapping some integers

Question

hello
I have this code below which maps out my string keys with string values; once it has maped them out it gets the string keys in the order that they are maped out at.
my problem is that i want to map some integers out with them ( int keys[]={0,1,2,3,4,5,6,7,8,9} )
How would i do this?
please help me

Hashtable ht2 = new Hashtable();
//Add vector to store results
Vector results2 = new Vector();
Object value2 = null;
String keys2[] = {"FirstName", "LastName", "Id", "Addr1", "Phone","County", "Postcode", "Country", "Addr2", "Town"};
//System.out.println(keys2);
String values2[] = {"ben", "ben", "ben", "mum", "ben","mum", "ben", "ben", "mum", "mum"};
// First, map keys to values in a hashtable
Hashtable hash2 = new Hashtable();
// the code matches values one by one for each of the keys
for(int i = 0; i < keys2.length; i++) {
hash2.put(keys2, values2[i]);
// Then we find each value and remove it from the hashtable
for(int j = 0; j < values2.length; j++) {
ht2 = (hash2);
value2 = (values2[j]);
Vector v = new Vector();
if( ht2.containsValue( value2 )) {
Enumeration e = ht2.keys();
while (e.hasMoreElements()) {
String tempkey2 = (String)e.nextElement();
String tempvalue2 = (String)ht2.get(tempkey2);
if (tempvalue2.equals(value2)) {
                         v.add(tempkey2);
                         ht2.remove(tempkey2);
results2.add(v);

As you probably know you cannot use integers as keys in your Hashtable object, because the keys have to be objects and int is a primitive type, not an object.
Use the Integer wrapper class:
Hashtable ht = new Hashtable();
ht.put(new Integer(1), "number one");
ht.put(new Integer(2), "number two");
To lookup a string:
int key = 2;
String value = (String)ht.get(new Integer(key));
