构造手机类，包含其配置信息：型号（字符串）、内存大小（整数）、存储空间（整数，GB为单位）、价格（整数）。提供带参数的构造函数，重写其equals方法，使得两个相同配置（型号、内存、存储相同即可，价格可不同）的手机为相等的手机。重写其toString函数，打印手机的配置信息，形式为CellPhone [model:xxx, memory:xxx, storage:xxx, price:xxx] main函数中从键盘读入两个手机对象，比较他们是否相等，输出他们的配置信息。 输入描述： 两个计算机对象，包含型号、内存、存储空间、价格 输出描述： 两个对象是否相等，两个对象的配置信息 裁判测试程序样例： import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); CellPhone c1 = new CellPhone(sc.next(),sc.nextInt(),sc.nextInt(),sc.nextInt()); CellPhone c2 = new CellPhone(sc.next(),sc.nextInt(),sc.nextInt(),sc.nextInt()); System.out.println(c1.equals(c2)); System.out.println(c1); System.out.println(c2); } } /* 你的代码将被嵌在这里 */ 输入样例： 在这里给出一组输入。例如： P20 8 64 4999 P20 8 64 4999 输出样例： 在这里给出相应的输出。例如： true CellPhone [model:P20, memory:8, storage:64, price:4999] CellPhone [model:P20, memory:8, storage:64, price:4999]
