我用Java寫了一個程序，允許用戶使用掃描器根據玩家的數量命名某些運動，反之亦然。我用幾乎所有我能想到的組合運行它，並且它工作正常。在提交作爲評分的課程項目之後，我們應該使用的自動化在線編譯器返回2個錯誤。教授告訴我，我的拼寫/標點符號應該有問題，但我無法確定。有人可以看看，並告訴我他們是否發現了什麼？所有幫助表示讚賞！我找不到我的拼寫/標點符號錯誤。我的代碼運行良好，但有一些錯誤

返回給你什麼錯誤？你確定他們不是警告嗎？ – Pshemo 2013-02-18 03:40:43
沒關係;我發現了錯誤。顯然，我忘記了「不正確」之後應該出現的感嘆號。在線編譯器認爲是拼寫錯誤並返回錯誤。我把它修好了，現在它完美運行。無論如何，儘管如此！ – 2013-02-18 03:49:46
但這並不會產生錯誤：/，在我的Eclipse中完美工作 – anshulkatta 2013-02-18 03:52:01
