java實(shí)現(xiàn)肯德基收銀系統(tǒng)

更新時(shí)間：2021年06月25日 17:07:58 作者：夠了.

這篇文章主要為大家詳細(xì)介紹了java實(shí)現(xiàn)肯德基收銀系統(tǒng)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

參考肯德基官網(wǎng)的信息模擬肯德基快餐店的收銀系統(tǒng)，合理使用C++或Java或Python結(jié)合設(shè)計(jì)模式（2種以上）至少實(shí)現(xiàn)系統(tǒng)的以下功能：

1.正常餐品結(jié)算和找零。

2.基本套餐結(jié)算和找零。

3.使用優(yōu)惠券購(gòu)買(mǎi)餐品結(jié)算和找零。

4.可在一定時(shí)間段參與店內(nèi)活動(dòng)（自行設(shè)計(jì)或參考官網(wǎng)信息）。

5.模擬打印小票的功能（寫(xiě)到文件中）。

小票信息保存

class print{ 
 String s=""; //存訂單信息
}

 public Hamburger createHamburger(print s,int kind,int num); //生產(chǎn)漢堡包
