Answer Posted / seamus barrett
An interface represents a contract between a class and its clients (the classes and functionality that consume the class). A class that implements an interface makes available to it's clients a collection of methods and properties as defined by the interface. As a class evolves (as the code changes) the contract between class and its client remains intact so long as the interface is unchanged. This allows a class to grow without requiring its clients to be rebuilt.
Difference? A class can be instantiated into an object that provides functionality to the instantiating function while an interface cannot be instantiated.
