程序名稱：模擬電梯系統
編碼時間：30-40個小時
參與人數：兩個
各自職責：zhidao（需求分析），Mars（編碼）
操作平臺：win7
編程語言：java swing
開發工具：Eclipse（Helios Service Release 1）
開發目的：業餘時間自我技能提升，通過嘗試不同的開發風格，掌握不同的開發技巧。還有與其他非工作夥伴共同開發，學會與不同類型夥伴交流。總之，主動提高對編程的瞭解，一切爲了在工作中能有更好的發展。
開發意義：不斷提升自己，超越自己。
開發理由：我經常會每天乘坐着電梯上下班，對電梯內部的實現原理尤其好奇，這是什麼樣的原理？我至少知道里面肯定是用到多線程知識，爲了那份好奇之心，我決定模擬一個小程序，滿足我的好奇之心。
項目簡介：
此項目模擬我們日常乘坐電梯的摸樣與實現原理，考慮到實現的複雜原因，我只是實現了一些簡單的功能。電梯一臺，樓層6層，每層樓有上下兩個按鈕（1層與6層只有一個），電梯內有7個按鈕（1個關門，6個各樓層位置按鈕），顯示牌一塊（記錄當前樓層與電梯運行狀態）。
此係統模擬的畫面，比較抽象，不過最關鍵是內部的實現思路。
鄙人把所有代碼貢獻出來，只希望看過的讀者，能給本人一點小建議。源碼如下：
