Question

我最近做了一个随机句子生成器。它从两个文件（名词和动词文件）中读取，并使用文件中的2个名词作为主语和对象，其间有动词。它作为一个java文件工作，但是当我按照wikihow上的教程将其转换为exe文件（link- http://www.wikihow.com/Create-an-Executable-File-from-Eclipse）时，程序将运行，但标签不会按指定的方式更改。我把名词和动词文本文件放在与exe文件相同的文件夹中，所以我不明白我的错在哪里。非常感谢任何帮助：D

谢谢， ArcWalrus

Answer 1

FileReader fileReader = new FileReader(fileName);
BufferedReader bufferedReader = new BufferedReader(fileReader);

应用程序资源在部署之前将成为嵌入式资源，因此立即开始访问它们是明智之举。必须通过URL而不是文件访问embedded-resource。有关如何形成网址，请参阅info. page for embedded resource。
