如何在Java中获取当前的工作目录? [英] How to get the current working directory in Java?

问题描述

我想使用Java访问我当前的工作目录.

我的代码:

 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);

输出:

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

我的输出不正确，因为C驱动器不是我的当前目录.

如何获取当前目录?

解决方案

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

这将打印从中初始化应用程序的完整绝对路径.

从文档:

java.io程序包使用当前用户目录解析相对路径名.当前目录表示为系统属性，即user.dir，是从其中调用JVM的目录.

I want to access my current working directory using java.

My code :

 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.

How to get the current directory ?

解决方案

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

This will print a complete absolute path from where your application was initialized.

From the documentation:

java.io package resolve relative pathnames using current user directory. The current directory is represented as system property, that is, user.dir and is the directory from where the JVM was invoked.
