Hi ,

Please give me a real time simple example for the below questions :

Where to use interface rather abstract class
Where to use abstract class rather interface

I need code snippet for both .

Which takes low memory and which performs well . Do I need to consider the design aspect also? What is the conceptual difference not the syntactical difference .
