Answer Posted / nick martin
"interface is collection of abstract method."
Ummm No... Perhaps you are thinking of an abstract class and
methods within.
An interface defines a class. A class that implements an
interface must implement all of the methods and properties
within the interface. Interfaces are commonly thought of as
a "Contract" as they guarantee that implementing class will
contain those methods and properties.
