1、在一个文件中创建一个商品类：package carlos.way;/*** 商品* @author Mr.zhang**/public class Shipping { String no; String name; int count; double price; double sum;}
2、在另一个文件中实现发票打印：package carlos.way;import java.math.RoundingMode;import java.util.Scanner;public class TrueList { public static void main(String[] args) { int i = 1; while (i != -1) {
3、 // 商品报价单 System.out.pr坡纠课柩intln("商品信息："); System.out.println("文明之光：￥59.00"); System.out.println("大学之路：￥72.00"); System.out.println("硅谷之谜：￥59.00"); System.out.println("输入1：开始购物"); Scanner sc1 = new Scanner(System.in); int no1 = sc1.nextInt(); if (no1 == 1) {
4、 // 订单信息 String[] up 屏顿幂垂= new String[6]; up[0] = "35201747366"; up[1] = "×××"; up[2] = "￥0.00"; up[3] = "￥0.00"; up[4] = "￥0.00"; up[5] = "2020-01-01"; // 文明之光 Shipping first = new Shipping(); first.no = "23494125"; first.name = "文明之光"; System.out.println("请输入第一件物品的购买的数量"); Scanner sc2 = new Scanner(System.in); first.count = sc2.nextInt(); first.price = 59.00; first.sum = first.count * first.price;
5、 // 大学之路 Shipping second = new Shipping(); second.no = "23750508"; second.name = "大学之路"; System.out.println("请输入第二件物品的购买的数量"); Scanner sc3 = new Scanner(System.in); second.count = sc3.nextInt(); second.price = 72.00; second.sum = second.count * second.price;
6、 // 硅谷之谜 Shipping third = new Shipping(); third.no = "23813967"; third.name = "硅谷之谜"; System.out.println("请输入第三件物品的购买的数量"); Scanner sc4 = new Scanner(System.in); third.count = sc4.nextInt(); third.price = 72.00; third.sum = third.count * third.price;
7、 // 结账or退出 System.out.println("输入2：结账，并打印小票"); System.out.println("输入3：不想买了，直接退出"); Scanner sc5 = new Scanner(System.in); int no2 = sc5.nextInt(); if (no2 == 2) {
