Getting the Current Working Directory in Java

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:WINDOWSsystem32
Current dir using System: C:WINDOWSsystem32

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

public class JavaApplication1 {
  public static void main(String[] args) {
       System.out.println("Working Directory = " +
              System.getProperty("user.dir"));
  }
}

这将从应用程序初始化的位置打印完整的绝对路径。

See: http://docs.oracle.com/javase/tutorial/essential/io/pathOps.html

Using java.nio.file.Path and java.nio.file.Paths , you can do the following to show what Java thinks is your current path. This for 7 and on, and uses NIO.

Path currentRelativePath = Paths.get("");
String s = currentRelativePath.toAbsolutePath().toString();
System.out.println("Current relative path is: " + s);

This outputs Current relative path is: /Users/george/NetBeansProjects/Tutorials that in my case is where I ran the class from. Constructing paths in a relative way, by not using a leading separator to indicate you are constructing an absolute path, will use this relative path as the starting point.

以下工作在Java 7及更高版本上（请参阅此处以获取文档）。

import java.nio.file.Paths;

Paths.get(".").toAbsolutePath().normalize().toString();
