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.
