不會連一句代碼都看不明白吧？
哪段程式看不明白說出來可以幫你看看解釋說明。要全部解釋，那就等待時間充裕的人現身吧。

我注釋一般這么寫
/**
* 1.拿到設備上生產的第一個工單資訊
* 2.判斷狀態(下發和中斷)的工單更新開始時間為當前系統時間,記錄工單結束時間
* 3.判斷是否是同組工單然后更新
* 4.根據設備id去查詢設備上所有的工單(除去已經更新過的) list
* 5.使用filter過濾同組工單
* 6.選擇最小序值更新開始時間為上一工單結束時間，記錄工單結束時間
* 7.移除該map避免重復6步時重新遍歷到

10樓編程好習慣uj5u.com熱心網友回復：
10樓可還行,不過要是游戲類這么寫,就跟寫文章一樣了,好幾千行代碼,寫注釋也要累死,哈哈
uj5u.com熱心網友回復：
單行注釋單獨寫一行。不要寫在代碼后面。uj5u.com熱心網友回復：
10樓編程好習慣uj5u.com熱心網友回復：
方法有注釋，關鍵環節有注釋uj5u.com熱心網友回復：
代碼即注釋嘛,我覺得注釋一般要加在特別難懂的代碼上,還有背景關系的介紹上,比如setXXX,我一看就知道賦值,就沒必要寫個注釋設定xxx值了
uj5u.com熱心網友回復：
是呀，注釋是對難于理解或有演算法的地方說明
uj5u.com熱心網友回復：
被前任程式員坑了幾次之后我現在寫代碼根本沒有注釋
