如何在Java中获取当前工作目录? [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 currentPath = new java.io.File(".").getCanonicalPath();System.out.println("当前目录:" + currentPath);String currentDir = System.getProperty(user.dir");System.out.println("当前目录使用系统:" + currentDir);

输出:

当前目录:C:WINDOWSsystem32当前使用系统的目录:C:WINDOWSsystem32

我的输出不正确，因为 C 盘不是我的当前目录.

如何获取当前目录?

解决方案

代码:

public class JavaApplication {公共静态无效主(字符串 [] args){System.out.println("工作目录 = "+ System.getProperty("user.dir"));}}

这将打印应用程序初始化的当前目录的绝对路径.

说明:

来自文档:>

java.io 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 并且是调用 JVM 的目录.

I want to access my current working directory using Java.

My code:

 String currentPath = new java.io.File(".").getCanonicalPath();
 System.out.println("Current dir:" + currentPath);

 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 the C drive is not my current directory.

How to get the current directory?

解决方案

Code :

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

This will print the absolute path of the current directory from where your application was initialized.

Explanation:

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.
