mapping a int value

[nicky sajdok]

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[i], 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);       
     }
}

ints are primitives, they can't be stored in hashmaps. Use the Integer wrapper class, and store those wrappers in the hashmap:

String  skey= "keystring";
Integer ival= new Integer(42);
Integer ikey= new Integer(54);
String  sval= "valstring";
hash.put(skey, ival);
hash.put(ikey, sval);

kind regards

Hello jos
I do not understand what you mean could you please descibe in more detail please
thankyou

You can create another hashtable that will map the values in the int array to either key or value
of your original key or value array.For this you have to convert int primitive type to Integer object because in the hashtable you can use only objects as key or value.
Then use this hashtable as key or value to construct the final hashtable.

Could you be so kind and give me some code examples as im stuck with this
thanks
