 * Description                                               : Java program to create an abstract class named Shape that contains an empty method named numberOfSides( ).
	 						       Provide three classes named Rectangle, Triangle and Hexagon such that each one of the classes extends
	                                                       the class Shape. Each one of the classes contains only the method numberOfSides( ) 
	                                                       that shows the number of sides in the given geometrical structures.
