用java实现简易外卖订餐系统,供大家参考,具体内容如下

一、使用技术

javaSE

二、实现功能

外卖订餐系统

具体要求如下:

使用选择结构,循环结构,数组的知识实现一个外卖订餐系统

三、运行效果图

1.订餐功能

2.查看餐袋

3.签收订单

4.删除订单

5.点赞

6.退出

代码实现

public class Order {

public static void main(String[] args) {

int zero = 1;

int x = 0;//订单数组下标

String[] name = new String[100];

int[] time = new int[100];//点餐时间

String[] menu = new String[100];

double[] price = new double[100];

int[] od = new int[100];//订单序号

String[] adress = new String[100];//送餐地址

int[] menuNum = new int[100];//点菜份数

String[] yuDing = new String[100];//订单状态

int a = 0;//点赞数

int b = 0;//点赞数

int c = 0;//点赞数

int panduan = 0;//判断是否有此订单
