6、运行结果图 程序源代码如下：下的 MobileManagement类：package class MobileMa nageme nt /* Defines the entry point of the application. */ public static void main(String args) Mobile mobile1 = new Mobile(E365, 1780);Mobile mobile2 = new Mobile(M330, 1450);(n ull, Mobile pho nes:nn+()+n+();下的Mobile 类：package class Mobile

7、 /* Holds the n ame of the mobile. */ private String name;/* Holds the price of the mobile. */ private float price;/* Creates a new mobile object. */ public Mobile(String name, float price) =n ame;=price;/* Gets the n ame of the mobile. */public Stri ng getName() return n ame;/* Gets the price of th

8、e mobile. */ public float getPrice() return price;运行结果如下:实验题3 有四个类，主类 Store在包中，Mobile、Mp3Player、Product 在包中，Mobile、Mp3Player 是 Product 的子类.基本要求设计类Mobile和类MP3Player,使它们和类 Product、Store 组成一个完整的程序，且运行结果如图所示。程序源码如下：中 Product 类：package abstract class Prouduct impleme nts Comparable /* Holds the n ame of

9、the product. */protected Stri ng n ame;/* Holds the price of the product. */protected float price;/* Holds the n umber of products. */protected static int cou nt;/* Create a new product object. */protected Prouduct() /* Gets the n ame of the product. */public Stri ng getName() return n ame;/* Gets t

10、he price of the product. */public float getPrice() return price;/* Gets the number of products. */ public static int getCount() return count;/* Compares this product with the given product. */ public int compareTo(Prouduct product) return new Float()pareTo(price);中 Mp3Player 类： package class MP3play

11、er extends Prouduct private String name;private float price; private int memory;public MP3player(String name,int memory,float price) */ public static void main(String args) E365,1780);Play,256, 930);Mobile mobile1 = new Mobile(China Mobile, Mobile mobile2 = new Mobile(China Mobile, M330,1450); MP3pl

12、ayer player1 = new MP3player(Meizo X3, 256, 399); MP3player player2 = new MP3player(Meizo E5, 512, 580); MP3player player3 = new MP3player(Xlive XM MP3 Prouduct prouducts=mobile1,mobile2,player1,player2, player3;(prouducts); String text = ;for(int index = 0; index ; +index) text += prouductsindex.to
