Finding absolute path

Question

I am looking at code new FileInputStream("config.properties").

I have the same file "config.properties" in multiple places in my project(doing windows file search) and I am now confused as to which one does this function call refer to. How do i get to know the absolute path of file?

I found this on the internet but this location doesnt look like the right answer.

"ClassName".class.getProtectionDomain().getCodeSource().getLocation().getPath() but this doesnt look it. Can you please correct it if I am wrong

use File file = new File("config.properties");file.getAbsolutePath(); — NullPointerException

Right. I was looking at FileInputStream class and tried if it had any method to find the absolute path but i can just pass the path name to File class and then find the answer. — Srujan Kumar Gulla

You can use File:

File f = new File("config.properties"); System.out.println(f.getAbsolutePath());

The path returned will be deduced from the current working directory.

thanks. Is there any way I can change and set a relative path for my program and start referencing other directories using that directory as base?

You can determine your program's current directory using new File(""). Then construct all path's from that.

sure. But can I change that reference point to some other directory which is more relevant?

@srujangulla, do you mean change the current working directory of the program? If so, I don't think it is possible (also see stackoverflow.com/questions/840190/…).

File f = new File("config.properties"); String dirPath = file.getParentFile().getAbsolutePath()
