用java写一个饮品店点单系统

这是一个简单的饮品店点单系统，使用Java编写，可以选择饮品种类、数量和加料，并计算总价格。

import java.util.Scanner;

public class DrinkShop {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        
        // 饮品种类
        String[] drinks = {"Bubble Milk Tea", "Green Tea", "Black Tea", "Milk Coffee"};
        // 饮品价格
        int[] prices = {20, 15, 15, 25};
        // 加料种类
        String[] toppings = {"Pearls", "Pudding", "Grass Jelly", "Coconut Jelly"};
        // 加料价格
        int[] toppingPrices = {5, 10, 8, 10};
        
        System.out.println("Welcome to Drink Shop!");
        
        // 选择饮品
        System.out.println("Please select a drink:");
        for (int i = 0; i < drinks.length; i++) {
            System.out.println((i + 1) + ". " + drinks[i] + " (" + prices[i] + " yuan)");
        }
        int drinkIndex = scanner.nextInt() - 1;
        System.out.println("You have selected " + drinks[drinkIndex] + ".");
        
        // 选择数量
        System.out.println("How many cups do you want?");
        int quantity = scanner.nextInt();
        System.out.println("You want " + quantity + " cups of " + drinks[drinkIndex] + ".");
        
        // 选择加料
        System.out.println("Do you want to add toppings? (y/n)");
        String choice = scanner.next();
        int toppingPrice = 0;
        if (choice.equalsIgnoreCase("y")) {
            System.out.println("Please select a topping:");
            for (int i = 0; i < toppings.length; i++) {
                System.out.println((i + 1) + ". " + toppings[i] + " (" + toppingPrices[i] + " yuan)");
            }
            int toppingIndex = scanner.nextInt() - 1;
            System.out.println("You have selected " + toppings[toppingIndex] + ".");
            toppingPrice = toppingPrices[toppingIndex];
        }
        
        // 计算总价格
        int totalPrice = prices[drinkIndex] * quantity + toppingPrice * quantity;
        System.out.println("Your total price is " + totalPrice + " yuan.");
        
        System.out.println("Thank you for shopping at Drink Shop!");
    }
