Hi Miga:
I tried the following code instead of the system out print.
// Retrieve an iterator to the hashset:
Iterator iter = hs.iterator();
// Extract elements from iterator. Note that the elements may not
// follow the order in which they are added to HashSet.
while(iter.hasNext())
{
System.out.print(iter.next());
iter.remove();
}
But it does not work!
Respects,

You don't need this
but you need:
myhashset.add(new MyClassObject("Eleven", 11));
Then you need some getters and setters in MyClassObject and to
override the toString method of MyClassObject so that you can get a
user-friendly output when printing the HashSet.

Use the hashset to display the value:
System.out.println(myHashSet);

This is the hexadecimal form of the hash code value for this object.
See hashCode and toString method of class Object.
