The interface keyword is used to declare an interface. Interfaces provide a construct for a programmer to create types that can have methods, properties, delegates, events, and indexers declared, but not implemented.
It is a good programming practice to give interfaces differing names from classes that start with an I and/or finish with ...able, like IRun or Runnable or IRunnable.
