java超市购物程序代码

以下是一个简单的 Java 超市购物程序代码示例：

import java.util.Scanner;

public class Supermarket {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // 商品清单
        String[] products = {"苹果", "香蕉", "饮料", "面包", "牛奶"};
        double[] prices = {3.5, 2.8, 4.0, 5.0, 2.0};

        // 购物车
        String[] cartProducts = new String[100];
        double[] cartPrices = new double[100];
        int cartCount = 0;

        // 显示商品清单
        System.out.println("欢迎光临超市！");
        for (int i = 0; i < products.length; i++) {
            System.out.println((i+1) + ". " + products[i] + " " + prices[i] + "元");
        }

        // 购物过程
        int choice;
        do {
            System.out.print("请选择要购买的商品编号（输入0结束购物）：");
            choice = scanner.nextInt();
            if (choice >= 1 && choice <= products.length) {
                cartProducts[cartCount] = products[choice-1];
                cartPrices[cartCount] = prices[choice-1];
                cartCount++;
                System.out.println(products[choice-1] + "已添加到购物车！");
            } else if (choice != 0) {
                System.out.println("没有该商品，请重新选择！");
            }
        } while (choice != 0);

        // 显示购物清单
        System.out.println("购物清单：");
        double totalPrice = 0.0;
        for (int i = 0; i < cartCount; i++) {
            System.out.println(cartProducts[i] + " " + cartPrices[i] + "元");
            totalPrice += cartPrices[i];
        }
        System.out.println("总计：" + totalPrice + "元");

        scanner.close();
    }
}

该程序使用数组来存储商品清单和购物车中的商品信息，使用循环和条件语句实现购物过程，并在购物结束后计算出总价并输出购物清单。可以根据实际需求对程序进行修改和扩展。
