Use Delegation to Share Implementation

The delegation "Delegation comprises of catching an operation on one object and sending it to other object which is part, or related to first object. In this method, only meaningful operations are delegated to second object, and meaningless operations can be banned from being inherited accidentally".

It is actuality that inheritance is an event for implementing generalization, in which behaviour of super class is shared by all of its subclasses. But, sharing of behaviour is justifiable only when a true generalization relationship come across, that is, only when it can be said which subclass is a form of the super class.
