Usage of Polymorphism feature in a project

[Ravi Kiran Va]

Hi ,

This is a discussion about making usage of Polymorphism feature in a java project .

Polymorphism is the feature that allows one interface to be used for general class actions.


By these i know that , if there is a one interface and there can be many implementation classes for it and depending upon the Object type instaniation the particular behaviour will be invoked .

But can you please tell me where actually or any scenario these will be useful in a project .



Thanks for reading and please share your ideas .

What do you use when you connect to DB2? Or Sybase? Or MySQL?

I need to write a DAO Layer ( I mean a interface and a number of implementation classes )
