java - 关于将 GUI 程序制作为 exe 文件.... (Java)

Question

我最近做了一个随机句子生成器。它从两个文件(一个名词和一个动词文件)中读取，并使用文件中的 2 个名词作为主语和宾语，中间有一个动词。它作为一个java文件工作，但是当我按照wikihow上的教程将其制作成exe文件(链接-http://www.wikihow.com/Create-an-Executable-File-from-Eclipse)时，程序将运行，但标签不会按照指定的方式更改。我的名词和动词文本文件与 exe 文件位于同一文件夹中，所以我不明白我的错在哪里。非常感谢任何帮助:D

谢谢，弧海象

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