吃货联盟订餐系统初始代码，基本实现初步功能，后续功能有待更新和优化，请各位看官不吝指点！！！！！

代码：

import java.util.Scanner; public class DingCan { // private static final String[] String = null;
    
        public static void main(String[] args) { /* * 初始化num0，num0=0时返回系统界面， flag标志为flag时退出整个系统，即为选项6的功能 */
            int num0 = -1; boolean flag = true; // 创建信息数组
            /* * xuhao 订单序号 * names 客户姓名 * menu 菜品名 * count 份数 * time 送餐时间 * address 送餐地址 * moneys 总金额 * state 订单状态 * MeHao 菜单序号 * menus 菜单 * Price 菜单单价 * Zan 菜品点赞数 */

         "红烧带鱼","鱼香肉丝","时令鲜疏"}; double[] Price = {
         38.0,15.0,10.0}; int[] Zan = {
