java實訓項目-模擬自動擋汽車
?
項目名稱:自動擋汽車操作模擬系統的設計與實現
英文名稱:Design and Implementation of Operation Simulation System aboutAutomatic Vehicle
1、功能描述:
1)汽車的操作正常為啟動(或熄火)、掛檔、制動、油門控制等操作;
2)掛檔實現自動擋的4檔操作,既駐車檔、倒車檔、空檔、行車檔;
3)使用圖形界面進行操作,汽車的狀態在圖形界面上顯示出來;
4)操作流程不合理,要有相應的控制;
5)附加功能:
(1)汽車的油也要進行控制,發動機需要消耗汽油,提供汽油報警功能;
(2)汽車的行程數進行控制,用戶界面顯示當前行程數;
6)正常操作流程為:啟動->剎車->掛檔->放剎車->汽車運動->加油門->剎車->駐車檔->熄火。行駛中嚴禁換擋,行駛檔位不能啟動。
參考文檔:
【1】系統類的API文檔,見CarApp.jar文件內的doc下的index.html文件
【2】系統運行效果,使用控制臺,輸入命令為:java –jar CarApp.jar
【3】汽車的運行可以選擇gif文件,從網上搜索關鍵詞“車運動? gif”或“動漫小車”等關鍵字搜索你喜歡的gif小車運動圖片,然後使用“工具GIF幀提取器 V1.1 綠色版.rar”提出圖片中的每幀圖片。
【4】系統的運行效果參考圖見圖1.
圖1:系統運行效果圖??
