I think this gets it done...

int eger = Integer.parseInt(data.getKey().toString());

Get the key, convert to string, then convert to int.

Have you tried generics?

Ok, I ran across another problem and I tested the same thing in your equation just to see if it would make a difference. How can I remove a value/key from the HashMap within a loop without getting this "ConcurrentModificationException"?

1. import java.util.*;
2. import java.util.Map.Entry;
3. 
   
4. Map<Integer, String> m = new HashMap<Integer, String>();
5. m.put(1, "one");
6. m.put(2, "two");
7. m.put(3, "three");
8. 
   
9. for (Entry<Integer,String> entry : m.entrySet()) {
10.   int k = entry.getKey();   
11.   String v = entry.getValue();
12.   println(k+" is "+v);
13.   m.remove(k);
14. }

Thank you very much good sir.
