We will go for an interface when we want to implement a
specific behaviour.

ex:
1.My class x implements IDisposable interface to handle
cleaup operation. I have to implement that behaviour by
implementing the method interface method Dispose()
explicitly in my code.

class x:IDisposable
{}
2.My class y implements IComparable interface to implement
sorting between a list of objects created of type y. Here I
have to implement CompareTo method.
