肯德基點餐收銀系統(java GUI實作)

1.系統介紹

同學們應該都去麥當勞或肯德基吃過快餐吧？請同學們參考肯德基官網的資訊模拟肯德基快餐店的收銀系統，合理使用C++/python/Java,結合設計模式（2種以上）至少實作系統的以下功能：

1.正常餐品結算和找零。

2.基本套餐結算和找零。

3.使用優惠劵購買餐品結算和找零。

4.可在一定時間段參與店内活動（自行設計或參考官網資訊）。

5.模拟列印發票的功能（寫到檔案中）。

2.系統設計

1.界面設計

采用java的Gui實作簡單的界面布局,界面上主要是圖檔和資料的顯示.我大多采用的是BorderLayout布局的方式,然後設定每個方位的大小.界面就很快做出來了.

發票資訊截圖:

2.背景設計

采用了抽象工廠模式和政策模式設計餐品的建立.

3.主要源代碼

主界面:
