酒店前台管理程序java

以下是一个简单的酒店前台管理程序的Java代码示例，其中包括开台点菜、维护菜品、签单、结账等功能：

import java.util.Scanner;

public class HotelFrontDesk {
    private static Room[][] rooms = new Room[5][10]; // 创建一个二维数组，存放房间信息

    public static void main(String[] args) {
        init(); // 初始化房间信息
        Scanner scanner = new Scanner(System.in);
        while (true) {
            System.out.println("欢迎使用酒店前台管理系统，请输入您的选择：");
            System.out.println("1. 开台点菜");
            System.out.println("2. 维护菜品");
            System.out.println("3. 签单");
            System.out.println("4. 结账");
            System.out.println("5. 退出");
            int choice = scanner.nextInt();
            switch (choice) {
                case 1:
                    openTable();

                case 2:
                    maintainDishes();
                    break;
