如何在 Java 中获取当前工作目录?

How to get the current working directory in Java?(如何在 Java 中获取当前工作目录?)

问题描述

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?

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.
