java.io.IOException: Permission denied in Java

Question

I am trying to create a file into the same folder in my project, but I am not able to create that file dynamically. I am trying this:

try {
            System.out.println("path"+System.getProperty("user.dir"));
            File file = new File("/textfile.txt");
            file.createNewFile();
            //file.createNewFile();
        } catch (Exception e) {
            e.printStackTrace();
        }

What I am getting error is this:

java.io.IOException: Permission denied

Any suggestion will be welcomed.

Solution

To create a File into the same folder in your project, your path has to be relative.

The path that you are giving is absolute, because it is starting from /. For your path to be relative, remove / from the path and try this :

File file = new File("textfile.txt");

i tried its working . :D but why its giving that time exception?

[codeMan]

you were trying to create a file in the root / directory of your linux computer and you may not be executing the java program as a root user, hence the exception.

but if i do like this '/' so that means i am trying to do in root directory is it?

[codeMan]

Yes, refer this : linuxnix.com/2012/07/…

ya that is right too. i can do that but thing is that for the absolute path was saying :) it was onto the root directory prob.
