這篇文章主要為你們詳盡介紹了java實現(xiàn)簡易外賣訂餐系統(tǒng)，文中示例代碼介紹的十分詳盡外賣訂餐系統(tǒng)，具有一定的參考價值，感興趣的男子伴們可以參考一下
用java實現(xiàn)簡易外賣訂餐系統(tǒng)，供你們參考，具體內(nèi)容如下
一、使用技術(shù)
二、實現(xiàn)功能
外賣訂餐系統(tǒng)
具體要求如下：
使用選擇結(jié)構(gòu)，循環(huán)結(jié)構(gòu)外賣訂餐系統(tǒng)，鏈表的知識實現(xiàn)一個外賣訂餐系統(tǒng)
三、運行療效圖
1.訂餐功能
2.查看餐袋
3.簽收訂單
4.刪掉訂單
5.點贊
6.退出
代碼實現(xiàn)
public class Order {
public static void main(String[] args) {
int zero = 1;
int x = 0;//訂單數(shù)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(shù)
String[] yuDing = new String[100];//訂單狀態(tài)
int a = 0;//點贊數(shù)
int b = 0;//點贊數(shù)
int c = 0;//點贊數(shù)
int panduan = 0;//判斷是否有此訂單
