clone() Method Without super.clone()

Opis

The product contains a clone() method that does not call super.clone() to obtain the new object.

All implementations of clone() should obtain the new object by calling super.clone(). If a class does not follow this convention, a subclass's clone() method will return an object of the wrong type.
