reading a file from current directory in java
提问by cMinor
I have a java project where I am reading a file. As the file is in the current directory I am doing this:
我有一个 java 项目，我正在读取一个文件。由于文件在当前目录中，我这样做：
String dataset = "./myFile.dat";
But I am getting: java.io.FileNotFoundExceptionsaying It can not find the file.
但我得到：java.io.FileNotFoundException说它找不到文件。
How to fix this? When I give entire path it works...
如何解决这个问题？当我给出整个路径时，它会起作用......
String dataset = "C:\eclipse\workspace\p1\src\myFile.dat";

If myFile.datis an application resource, it should be included in a Jar that is on the run-time class-path of the application. Then an URL to the resource can be formed using..
如果myFile.dat是应用程序资源，则应将其包含在应用程序运行时类路径上的 Jar 中。然后可以使用..形成资源的 URL。
URL urlToData = this.getClass().getResource("path/in/jar/to/myFile.dat");
Don'trely on the user.dirproperty. Depending on how the app. is started, it might point somewhere very different to the directory of the application or data.
不要依赖user.dir财产。取决于应用程序的方式。启动时，它可能指向与应用程序或数据目录非常不同的某个地方。
