奶茶点单程序Java

以下是一个简单的奶茶点单程序的Java代码实现：

import java.util.Scanner;

public class MilkTeaOrder {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        String[] milkTeas = {"原味奶茶", "四季奶青", "珍珠奶茶", "红豆奶茶", "芒果奶茶"};
        double[] prices = {9.9, 10.5, 11.0, 11.0, 12.0};
        int[] amounts = new int[milkTeas.length];

        System.out.println("欢迎光临！以下是我们的奶茶菜单：");
        for (int i = 0; i < milkTeas.length; i++) {
            System.out.println(i + 1 + ". " + milkTeas[i] + "\t\t" + prices[i] + "元/杯");
        }

        while (true) {
            System.out.print("请输入您要购买的奶茶序号（输入0结束点单）：");
            int choice = input.nextInt();
            if (choice == 0) {
                break;
            }
            System.out.print("请输入购买数量：");
            int amount = input.nextInt();
            amounts[choice - 1] += amount;
        }

        System.out.println("您的订单：");
        double total = 0;
        for (int i = 0; i < milkTeas.length; i++) {
            if (amounts[i] > 0) {
                System.out.println(milkTeas[i] + "\t\t" + prices[i] + "元/杯\t\t" + amounts[i] + "杯\t\t" + prices[i] * amounts[i] + "元");
                total += prices[i] * amounts[i];
            }
        }
        System.out.println("总计：" + total + "元。");
        System.out.println("感谢惠顾，欢迎下次光临！");
    }
}

该程序会先输出奶茶菜单，然后循环让用户输入要购买的奶茶序号和数量，直到用户输入0为止。程序会记录用户购买的每种奶茶的数量，并在最后输出整个订单，并计算出总金额。
