用JAVA写一个奶茶点单系统

好的，下面是一个简单的奶茶点单系统的JAVA代码：

import java.util.Scanner;

public class MilkTeaOrderingSystem {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int choice;
        int sugarLevel;
        int iceLevel;
        boolean addPearl;
        double price;

        System.out.println("欢迎来到奶茶点单系统！");

        do {
            System.out.println("请选择您要的奶茶口味：");
            System.out.println("1. 原味奶茶");
            System.out.println("2. 珍珠奶茶");
            System.out.println("3. 草莓奶茶");
            System.out.println("4. 巧克力奶茶");
            System.out.println("0. 结束点单");

            choice = input.nextInt();

            switch (choice) {
                case 1:
                    price = 10.0;
                    break;
                case 2:
                    price = 12.0;
                    System.out.println("是否加珍珠？(1-是，0-否)");
                    addPearl = (input.nextInt() == 1);
                    if (addPearl) {
                        price += 2.0;
                    }
                    break;
                case 3:
                    price = 15.0;
                    break;
                case 4:
                    price = 18.0;
                    break;
                case 0:
                    System.out.println("谢谢使用！");
                    return;
                default:
                    System.out.println("输入有误，请重新输入！");
                    continue;
            }

            System.out.println("请选择甜度：");
            System.out.println("1. 正常甜");
            System.out.println("2. 七分甜");
            System.out.println("3. 五分甜");
            System.out.println("4. 三分甜");
            System.out.println("5. 不加糖");

            sugarLevel = input.nextInt();

            switch (sugarLevel) {
                case 1:
                    price += 0.5;
                    break;
                case 2:
                    price += 0.3;
                    break;
                case 3:
                    price += 0.1;
                    break;
                case 4:
                    price -= 0.1;
                    break;
                case 5:
                    break;
                default:
                    System.out.println("输入有误，请重新输入！");
                    continue;
            }

            System.out.println("请选择冰量：");
            System.out.println("1. 正常冰");
            System.out.println("2. 少冰");
            System.out.println("3. 去冰");
            System.out.println("4. 加热");

            iceLevel = input.nextInt();

            switch (iceLevel) {
                case 1:
                    break;
                case 2:
                    price += 0.2;
                    break;
                case 3:
                    price -= 0.5;
                    break;
                case 4:
                    price += 0.5;
                    break;
                default:
                    System.out.println("输入有误，请重新输入！");
                    continue;
            }

            System.out.printf("您选择的是%d号奶茶，甜度为%d，冰量为%d，价格为%.2f元\n", choice, sugarLevel, iceLevel, price);
        } while (choice != 0);
    }
}

这个程序模拟了一个简单的奶茶点单系统，用户可以选择奶茶口味、甜度、冰量和是否加珍珠，程序会根据用户的选择计算出价格并输出。用户可以选择结束点单。
