我更好地從一開始就解釋情況。我想換一個.jar文件的分辨率，所以我Java Decompiler反編譯，然後我去了記事本+ +和做了一個小編輯，在2號線爲.java文件：java - 如何用Eclipse或NetBeans編譯一個沒有錯誤的java文件？
paramGraphics.setClip(0, 0, 176, 208);
這樣：
paramGraphics.setClip(0, 0, 320, 240);
和：
paramGraphics.setClip(0, 0, 176, 208);
這樣：
paramGraphics.setClip(0, 0, 320, 240);
然後保存。之後，我想將該文件編譯到一個類中。我嘗試使用javac命令，沒有工作，並顯示100錯誤。它沒有編譯。十個使用的NetBeans。相同的結果，它沒有編譯。
這是NetBeans中的編譯器輸出：

我怎樣才能重新編譯我的文件上課嗎？我對Java不太瞭解，所以我是一個新手。誰能幫我？
在此先感謝
更新！

刪除所有錯誤。添加所有依賴項。 –
你必須給所有依賴於它，或者它會更清楚，我當u發表您的錯誤，有 – Tenacious
我打賭，所有的（大部分）你的錯誤是由於缺少資源。至少，您需要讓您的'javac'命令訪問任何其他需要可用的JAR和資源才能構建它。如果你的反編譯器爲你提供了導入名稱，這些包應該給你一個線索。這是一個完整的自定義構建，並且超出了本網站的範圍。 –
