In Java, the current working directory can be found using the following code:
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 the current user directory. The current directory is represented as a system property, that is, user.dir
and is the directory from where the JVM was invoked.
Method #2:
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 is for 7 and on, and uses NIO.
Path currentRelativePath = Paths.get("");
String s = currentRelativePath.toAbsolutePath().toString();
System.out.println("Current absolute path is: " + s);
This outputs:
Current absolute 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.
Method #3:
The following works on Java 7 and up:
import java.nio.file.Paths;
Paths.get(".").toAbsolutePath().normalize().toString();
Getting current working directory in Java:
This will give you the path of your current working directory:
Path path = FileSystems.getDefault().getPath(".");
And this will give you the path to a file called “Foo.txt” in the working directory:
Path path = FileSystems.getDefault().getPath("Foo.txt");
Edit : To obtain an absolute path of current directory:
Path path = FileSystems.getDefault().getPath(".").toAbsolutePath();
* Update * To get current working directory:
Path path = FileSystems.getDefault().getPath("").toAbsolutePath();
Answer #4: Current working directory in Java
Java 11 and newer
This solution is better than others and more portable:
Path cwd = Path.of("").toAbsolutePath();
Or even
String cwd = Path.of("").toAbsolutePath().toString();
On Linux when you run a jar file from terminal, these both will return the same String
: “/home/CurrentUser”, no matter, where youre jar file is. It depends just on what current directory are you using with your terminal, when you start the jar file.
Paths.get("").toAbsolutePath().toString();
System.getProperty("user.dir");
If your Class
with main
would be called MainClass
, then try:
MainClass.class.getProtectionDomain().getCodeSource().getLocation().getFile();
This will return a String
with the absolute path of the jar file.
