在 Java 中获得当前的工作目录

Question

I want to access my current working directory using

 String current = new java.io.File( "." ).getCanonicalPath();
        System.out.println("Current dir:"+current);
 String currentDir = System.getProperty("user.dir");
        System.out.println("Current dir using System:" +currentDir);

OutPut:

Current dir: C:\WINDOWS\system32
Current dir using System: C:\WINDOWS\system32

My output is not correct because C drive is not my current directory. Need help in this regard.

Answer 1

Current working directory is defined differently in different Java implementations. For certain version prior to Java 7 there was no consistent way to get the working directory. You could work around this by launching Java file with -D and defining a variable to hold the info

Something like

java -D com.mycompany.workingDir="%0"

That's not quite right, but you get the idea. Then System.getProperty("com.mycompany.workingDir")...
