所以我尝试导入我的 res 文件夹中的文件,到目前为止我一直在使用这种方法。
File f = new File("src/resources/levels/" + part + "/" + filename + ".txt");
但是在我编译它并将它作为一个 jar 运行之后它不再工作,我理解这是因为它在磁盘上而不是 jar 上寻找文件,我在导入我的图像和字体时遇到了同样的问题,但我设法修复那但是经过研究,我找不到不同的方法。运行 jar 时我没有收到任何错误,而是没有显示信息,这在 eclipse 中编译和运行良好。
这是我的资源文件:

那么我将如何导入我的文件以便在编译成 jar 时可以读取它?
