    hi, Can anyone tell me how can I list the key names in a hashtable. To access a value of a given key is simple(HashTable["key"].tostring()). But I want to list all the keys in a hashtable. how can that be possible. Regards Royal

    Hi, yes, it can be done by an ArrayList import java.util.ArrayList; import java.util.HashMap; public class Test { public static void main(String[] args) { Object anObject = new Object(); Object anotherObject = new Object(); HashMap hm = new HashMap(); ArrayList keyList = new ArrayList(); hm.put("Key1", anObject); hm.put("Key2", anotherObject); keyList.addAll(hm.keySet()); System.out.println(keyList); } } The Result: [Key2, Key1]
