What is the use of Interface ?
Java acheive inheritance using two notions : By 
extending the class and implementing the 
interace. When you "implement" an interface, you 
are stipulating that your class adheres to the 
"contract" of the interface that you specified. 
Use interfaces to say "What objects can do" or 
"What can be done to an object. "Interfaces are 
intended to define the what without defining the 
how. Interfaces provide a form of multiple 
inheritance. A class can extend only one other 
class. Interfaces are limited to public methods 
and constants with no implementation.
