Question

As a example:

public class Hello {
    public static void main(String[] args) {
        try {
            OutputStream os = new FileOutputStream(new File("c.txt"));
            try {
                os.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

Why was c.txt generated in the root path of current project other then the same path of the java file?

thanks.

Answer 1

Because the root of your project is your current working directory when starting the JVM.
You can check the user.dir system property to see what is your current working directory. If you access a file without a leading slash (Unix) or drive specifier/backslash (Windows), the files will be created relative to your current working directory.
