// TIJ4 Chapter Polymorphism, Exercise 9, page 289
/* Create an inheritance hierarchy of Rodent:Mouse, Gerbil, Hamster, etc. In the
* base class, provide methods that are common to all Rodents, and override these
* in the derived classes to perform different behaviors depending on the
* specific type of Rodent. Create an array of Rodent, fill it with different
* specific types of Rodents, and call your base-class methods to see what 
* happens.
*/
/* Solution includes, in same package: 
* import java.util.*;
* public class RandomRodentGenerator {
*	private Random rand = new Random();
*	public Rodent next() {
*		switch(rand.nextInt(3)) {
*			default:
*			case 0: return new Mouse();
*			case 1: return new Rat();
*			case 2: return new Squirrel();			
*		}
*	}
