Polymorphism is a unique feature of OOPs. By using this featur we can use a particular interface for a generalised class of actions The exact nature of the situation can determine the specifi actions. In a nutshell we can say that polymorphism is a syste that includes a single interface and multiple methods. We ca design a general interface to a group that includes multiple activ ities. Many complexities can be lessened as here we can apply a single interface for multiple actions. The 'method' can specify the actions that are to be applied via the common interface.
