java實現簡易外賣訂餐系統
用java實現簡易外賣訂餐系統，供大傢參考，具體內容如下
一、使用技術
javaSE
二、實現功能
外賣訂餐系統
具體要求如下：
使用選擇結構，循環結構，數組的知識實現一個外賣訂餐系統
三、運行效果圖
1.訂餐功能
2.查看餐袋
3.簽收訂單
4.刪除訂單
5.點贊
6.退出
代碼實現
public class Order {
public static void main(String[] args) {
int zero = 1;
int x = 0;//訂單數組下標
String[] name = new String[100];
int[] time = new int[100];//點餐時間
String[] menu = new String[100];
double[] price = new double[100];
int[] od = new int[100];//訂單序號
String[] adress = new String[100];//送餐地址
int[] menuNum = new int[100];//點菜份數
String[] yuDing = new String[100];//訂單狀態
int a = 0;//點贊數
int b = 0;//點贊數
int c = 0;//點贊數
int panduan = 0;//判斷是否有此訂單
