制作人：尹子杰，朱健釗

項目簡介：

團隊選擇任務為小游戲，選擇具體游戲為飛機大戰，不僅是因為編寫出游戲有一定的挑戰性和難度，是對我們本學期java學習的檢測，更能通過本次代碼編寫找到自身更多不足之處，也讓我們更加了解了我們所學的知識點的應用。我們通過努力完成了這個項目，其中不足的地方也請老師指出我們改正。

項目關鍵技術：

java變量、java數據類型、判斷語句、循環結構、數組、Java集合、簡單窗口創建、圖形圖片繪制、雙緩存技術、事件-鼠標和鍵盤事件、awt抽象窗口工具包、部分復雜算法、大部分注釋、GUI界面、面向對象程序設計、線程等

開發工具：idea

開發環境：jdk11

項目需求分析：

1.方法簡單，游戲方式簡單，更容易上手游玩。

2.能夠方便操作，可以用鼠標靈活操作。
