Explanation

The dynamic dispatch process is a process which is applicable when  a call to the overridden method is resolved at runtime rather than at compile time. This will be used as part of polymorphism concept. In the dynamic dispatch process, a reference variable calls the overridden method of the superclass but not the subclass because it doesn't know anything about subclass.
