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.
